Description

Toner for developing electrostatic latent image, toner Cartridge and image processing system
Technical field
The present invention relates to a kind of toner for developing electrostatic latent image, toner Cartridge and image processing system, as adhesive resin, the dry toner purposes that the conduct in xerography, electrostatic recording or videograph etc. of this adhesive resin is used for the development of electrostatic image or magnetic sub-image is useful to described toner for developing electrostatic latent image with vibrin.
Background technology
Up to now, in order to improve the low-temperature fixing performance of toner, known use vibrin is as bonding agent (with reference to patent documentation 1 and 2).In order further to improve the low-temperature fixing of toner, be necessary to reduce molecular weight or glass transition temperature (Tg), but have the problem of the anti-adhesive difference of the toner under the hot and humid degree this moment.In addition, if use such resin, then exist toner components to be bonded on carrier or the development sleeve and cause the problems such as charged ability reduction of developer.Further, this charged ability be reduced under the hot and humid environment or the low temperature and low humidity environment under and under hi-vision area output, As time goes on begin to become remarkable.Therefore, expectation is provided under the environment for use of the no problem but wider model of user of common environment for use, can be with stable toner and the image processing system of exporting high quality images of any one using method.
In addition,, prevent background stained (backgroundsmear), the known technology (with reference to patent documentation 3) that contains charging control agent (charged controlling agent) in the bonding agent that makes for the charging property that improves toner, charged stability.But charging control agent is compared with vibrin, and the low-temperature fixing performance is low, owing to be present in the toner, has the ill-effect that hinders the low-temperature fixing performance that vibrin had.Therefore, in order further to improve the low-temperature fixing of toner, be necessary charging control agent is dispersed in the toner equably, thereby can bring into play sufficient chargeding performance with amount still less.
The developer that in electrofax, electrostatic recording, xeroprinting etc., uses, in this development step, for example in case attached on the photoreceptor that is formed with electrostatic image, then in transfer step, be transferred on the recording medium such as paper from photoreceptor after, photographic fixing is on paper in the photographic fixing step.At this moment, the developer of the electrostatic image development on the sub-image maintenance face will be formed at, the known single component class developer (magnetic color tuner, nonmagnetic toner) that contains the bi-component class developer of carrier and toner and do not need carrier as being used for.In the bi-component visualization way, because toner particle is attached on the carrier surface, developer degradation, in addition, because the toner concentration that only consumes in toner, the developer reduces, thus must keep mixing ratio with carrier with certain ratio, so developing apparatus is than relatively large.On the other hand, in the single component development mode,, install more miniaturization by the multifunction of developer roll etc.
In recent years, the OAization of office or colorize further develop, be not only the duplicating of the original copy that only contains literal in the past, and printer output such as the chart made from personal computer, the image of taking with digital camera, the diagram original copy that reads by scanner etc., increase as the chance of many duplicating such as data of displaying usefulness.For the image of printer output, image, line image, half tone image etc. mix in an original copy on the spot complicated structure, has also improved for the requirement and the multiduty requirement of the high reliability of image.
The electronic camera technology of use single component class developer in the past is categorized as the magnetic single component development mode of using magnetic color tuner and the non-magnetic mono-component visualization way of using nonmagnetic toner.The magnetic single component development mode, owing to use the inner developer carrier that is provided with magnetic field generation device such as magnet, keep containing the magnetic color tuner of magnetics such as magnetic iron ore, carry out thin layerization and develop, so a large amount of practicability in miniprinter etc. in recent years by the layer thickness control parts.But, what magnetic mostly was greatly coloured (black system), there is the shortcoming that is difficult to colorize.
On the other hand, the non-magnetic mono-component visualization way is crimped on toner replenishing roller etc. on the developer carrier because toner does not have magnetic force, supplies with toner on developer carrier, and static keeps, and by layer thickness control parts thin layerization, develops.Owing to wherein do not contain coloured magnetic, have the advantage that can realize colorize, in addition because developer carrier does not use magnet, can further lightweight of implement device and cost degradation, in small-sized panchromatic printer etc., be practical in recent years.
In addition, in the bi-component visualization way, since use carrier as toner charged, transmit material with toner and carrier after the inner fully stirring of developer, mixing, be sent on the developer carrier and develop, even also can keep stable charging property and transmission property, in addition also easily corresponding to developing apparatus at a high speed so the long time uses.
In contrast to this, present situation is: in the single component development mode, the problem that should improve is still a lot.In the single component development mode owing to do not have such stable charged of carrier or transmit material, therefore long-time use or be easy to generate during high speed charged bad, transmit bad.Promptly, in the single component development mode, after transmitting toner on the developer carrier, with the layer thickness control parts toner thin layerization is developed, but because the contacting of toner and frictional electrification parts such as developer carrier, layer thickness control parts, frictional electrification time are very short, compare with the bi-component visualization way of using carrier, easily form low charged, contrary charged toner mostly.
Particularly in the non-magnetic mono-component developing method, usually adopt by at least one toner transfer member and transmit toner (developer) and make the method that is formed on the latent electrostatic image developing on the latent image carrier, but the toner bed thickness on toner transfer member surface must be extremely thin at this moment by the toner that transmits.This also is suitable under the situation of the very little bi-component class developer of carrier use diameter, in addition, when particularly using single component class developer and using the high toner of resistance, owing to be necessary to make this toner charged according to developing apparatus, so the bed thickness of toner must be extremely thin.This is that it is charged that toner layer integral body is difficult to homogeneous because if toner layer is very thick, then only the near surface of toner layer is charged.Therefore, require toner is kept charged more rapidly speed and suitable carried charge.
Therefore, added charged controlling agent and adjuvant for the charged stabilization that makes toner in the past.Above-mentioned charged controlling agent plays the frictional electrification amount of control toner, the effect that keeps its frictional electrification amount.As the representational charged controlling agent of negative charging, coordination compound that can enumerate the metal complex, two azo-compounds of slaine, the dicarboxylic acid of for example monoazo dyes, salicylic acid, naphthoic acid, dicarboxylic acid, obtains by boron etc.In addition, as the representational charged controlling agent of Positively chargeable, can enumerate for example quarternary ammonium salt compound, imidazolium compounds, nigrosine, azines etc.
But, in these charged controlling agents, existing to have coloured charged controlling agent, the charged controlling agent that can not be used for color toner is many.In addition, in these charged controlling agents, since poor to the compatibility of adhesive resin, easily break away from the charged big relevant charged controlling agent that is present on the toner surface, and the charged generation of toner is uneven.In addition, shortcomings such as the pollution of the easy generation of existence development sleeve or photoreceptor film forming.
Therefore, though existed the initial stage to obtain excellent image in the past, image quality changes, produces the phenomenon of background stained or unclear (Pot そ つ I) lentamente.Particularly if be applied in the color photocopying, if use continuously on supply toner limit, limit, then the carried charge of toner reduces, form tone and the remarkable different image of the copy image at initial stage, not anti-long use is only carried out about thousands of duplicating and just must be changed the image-forming block that is called as handle box in advance.Therefore, big to the load of environment, the user feels trouble.Further,, consider from the security aspect in recent years, becoming problem because these boxes contain heavy metals such as chromium mostly.
Therefore, as the material that improves the problems referred to above, known improvement is to the compatibility of adhesive resin, the transparency of toner fixing image, the resin strip controling agent of security.These resin strip controling agents since with the compatibility excellence of adhesive resin, therefore in stable charging property, also excellent aspect transparent.But if compare with the toner of the slaine/metal complex that uses monoazo dyes, salicylic acid, naphthoic acid, dicarboxylic acid, then there is the shortcoming of carried charge and charged velocity contrast in these resin strip controling agents.In addition, by increasing the addition of resin strip controling agent, charging property improves, but toner fixation performance (low-temperature fixing, anti-hectograph print through (offset) property) is had harmful effect.Further, the environmental stability of the carried charge of these compounds (moisture resistance) is big, therefore has the problem (with reference to patent documentation 4~7) that easily produces background stained (photographic fog).
Therefore, the monomer and multipolymer of acylate such as sulfonate groups have been proposed to contain with aromatic monomer of electron withdraw group.Yet, though owing to be considered to guarantee sufficient carried charge because of the hydroscopicity or the cohesive of the monomer that contains acylate such as above-mentioned sulfonate groups, but the dispersion in adhesive resin is insufficient, suppress for a long time toner charged inequality, prevent the effect insufficient (with reference to patent documentation 8~11) of film forming etc. to development sleeve or photoreceptor.
In addition, in order to improve to compatibility as the styrene resin and the polyester resin of adhesive resin, proposed respectively to contain monomer, aromatic monomer and the styrene monomer of acylates such as sulfonate groups or the multipolymer of polyesters monomer, but the maintenance of the long charged amount of these materials, prevented that development sleeve or photoreceptor film-formation result are insufficient with electron withdraw group.Particularly as the full-color toner adhesive resin, for considering that from colour rendering, image intensity aspect preferred polyester resin or polyol resin are inadequate.
In addition, in recent years printer needs to enlarge, the miniaturization of device, high speed or cost degradation development, device is begun higher reliability of requirement and long lifetime, toner is required to keep various characteristics for a long time, but these resin strip controling agents can not keep its charged control effect, exist to pollute development sleeve or layer thickness control parts (scraper plate or roller) and make the chargeding performance of toner reduce or produce the problem of photoreceptor film forming.
In addition,, form the technology of using a spot of developer to develop at short notice, require electrically (band Electricity founds Ga り on the Chi) more excellent developer of initial strip owing to miniaturization, high speed.For development, when proposing two-component developing agent, monocomponent toner, various visualization way have been proposed, but can miniaturization and lightweight aspect etc. excellence, do not use carrier and the non-magnetic mono-component finished to be developed in the printer use be suitable.In this visualization way and since toner to developer roll the supply or the toner retentivity of developer roll poor, force toner coated or by the toning dosage on the scraper plate control developer roll to developer roll.Toner film forming on developer roll easily produces the lost of life of developer roll or the carried charge problem of unstable of toner as a result.In addition, can not carry out good development thus.Therefore, in the color toner of non-magnetic mono-component development usefulness, except the necessary characteristic of common color toner, the situation of the poor heat resistance of the binder resin that uses in the toner is many, is easy to generate toner to film forming of developer roll etc.
But in the example of above-mentioned patent documentation 1~4 record, there is the shortcoming of carried charge, charged velocity contrast.If prevent these shortcomings and increase the addition of resin strip controling agent that though then charging property is improved, (low-temperature fixing, anti-print through) has harmful effect to the toner fixation performance.Further, the environmental stability of the carried charge of these compounds (moisture resistance) is big, therefore has the shortcoming that easily produces background stained (photographic fog).
In addition, in the above-mentioned patent documentation 8~11, guarantee sufficient carried charge, but the dispersion in adhesive resin is insufficient, exists and suppress charged inequality, prevent the inadequate problem of effect the film forming of sleeve and photoreceptor by hydroscopicity or cohesive.
In addition, in the image that is undertaken by the electrofax mode forms, on image-carriers such as photoconductivity material, form sub-image by static charge, for this electrostatic latent image, after adhering to charged toner particle formation visual image, this toner image is transferred on the recording medium such as paper, carries out photographic fixing, form output image.In recent years, use the duplicating machine of electrofax mode or the technology of printer, develop rapidly to panchromatic from monochrome, there is the trend of expansion in panchromatic market.
Form in the coloured image by panchromatic xerography, generally with the color toner of trichromatic yellow, magenta, these three kinds of colors of cyan or add the color toner lamination of four kinds of colors that black arranged and obtain therein and carry out the reproduction of all colours.Therefore, in order to obtain the full-colour image of colorrendering quality excellence, distinctness, except being necessary to make the toner image surface of photographic fixing for to a certain degree level and smooth, and reduce outside the light scattering etc., in order to ensure colorrendering quality, pigment is dispersed in the toner equably and disperse after the not obvious cohesion of pigment and keep differential to loose.
Particularly in order to reproduce people's colors such as the colour of skin, be necessary to use the substractive color mixing of being undertaken to come apparent color, study as problem to yellow uitramarine, magenta pigment and as the best of breed of the resin that disperses parent by the coincidence of Yellow toner and pinkish red toner.
For example, the pinkish red toner of electrostatic image development is disclosed in the patent documentation 12, it is the method for producing toner and toner that dissolving contains the polyester resin of the modification that can carry out the urea bonding in organic solvent, make it in water-medium, carry out addition polymerization, the toner that contains colorant at least that the solvent of this dispersion liquid is removed and washed and obtains again, wherein, described colorant is the compound of regulation.
In addition, the pinkish red toner of a kind of electrophotography is disclosed in the patent documentation 13, it is in the pinkish red toner of the electrophotography that contains binder resin and colorant at least, at least contain have the regulation structure aphthols pigment as above-mentioned colorant, and the shape coefficient SF1 of toner is 110~140, volume average particle size is 2~9 μ m.
But actual conditions are: when only utilizing said method, can not prevent because the problem of the colorrendering quality difference that the cohesion again of the pigment in the toner is caused can not realize the colorrendering quality of image, particularly can not verily reproduce people's the colour of skin.

Among the present invention,, consider, preferably use above-mentioned polycondensation vibrin from colour rendering, image intensity aspect as the full-color toner adhesive resin.Coloured image is because several plies of several toner layers, and the toner layer thickening produces because crackle, the defective of the insufficient image that causes of intensity of toner or lose suitable gloss.Therefore, use above-mentioned vibrin in order to keep suitable gloss or excellent intensity.
The above-mentioned vibrin of such adhesive resin does not especially preferably have the insoluble composition of THF, and in the molecular weight distribution of gel permeation chromatography, mass molecular weight is 5 * 10 2The content of following composition is below the 4 quality %, and in mass molecular weight 3 * 10 3~9 * 10 3The zone in have the vibrin at a peak.If there is the insoluble composition of THF, then glossiness reduces, and the transparency reduces simultaneously, can not obtain high quality images when using the OHP sheet.Toner of the present invention for the molecular weight distribution of adhesive resin, is 5 * 10 with mass molecular weight preferably 2Following quality % is defined in below 4%, and in addition, preferably the ratio with weight-average molecular weight (Mw) and number-average molecular weight (Mn) is defined in 2≤Mw/Mn≤10, thus, is difficult for producing the film forming to scraper plate, sleeve etc.In addition, if mass molecular weight is 5 * 10 2Following composition is more than the 4 quality %, then owing to long-time the use polluted scraper plate or sleeve, easily produces film forming.
In addition, the molecular weight distribution of the adhesive resin that uses in the toner of the present invention is by the following mensuration of gel permeation chromatography.In 40 ℃ hot cells (heat chamber), make post stable, in the post under this temperature, flow through THF, inject the THF sample solution 200 μ l that sample solution concentration is adjusted into the parent toner of 0.05~0.6 quality % and measure with the flow velocity of per minute 1ml.The THF sample solution is removed the insoluble composition of THF with the phase chromatography-use filtrator of 0.45 μ m before injection.
In the molecular weight determination of the sample of toner, the molecular weight distribution that sample has is calculated by the logarithm value of the typical curve of making by several monodisperse polystyrene standard samples and the relation of calculation times.As the polystyrene standard sample that standard curve making is used, the molecular weight that for example uses PressureChemical Co. or Tosoh Co. to make is 6 * 10 2, 2.1 * 10 3, 4 * 10 3, 1.75 * 10 4, 5.1 * 10 4, 1.1 * 10 5, 3.9 * 10 5, 8.6 * 10 5, 2 * 10 6, 4.48 * 10 6The polystyrene standard sample, preferably use the polystyrene standard sample about 10 at least.In addition, detecting device uses RI (refractive index) detecting device.And adhesive resin has or not the insoluble composition of THF to judge when the THF of molecular weight distribution determination sample solution prepares.That is, the filter element of 0.45 μ m is installed in the top of syringe, when in syringe, extruding liquid, then judges the insoluble composition of no THF if filtrator does not block.
In addition, the adhesive resin that uses among the present invention endothermic peak that preferably adopts differential scanning calorimeter (DSC) to measure is 60~70 ℃.If above-mentioned endothermic peak is lower than 60 ℃, then influential to the toner keeping quality, might produce problems such as toner solidifies in box or in the hopper.On the other hand,, then influence the toner productivity, might produce the problems such as feed reduction when pulverizing if surpass 70 ℃.The endothermic peak that adopts differential scanning calorimeter (DSC) to measure, for example, the RigakuTHRMOFLEX TG8110 that makes by Rigaku Denki Co., Ltd measures under the condition of 10 ℃/min of programming rate, reads the very big peak of main body of endothermic curve.

In addition, when the above-mentioned vibrin that uses among the present invention particularly used aftermentioned resin strip controling agent, in the interaction of this resin strip controling agent and adjuvant, acid number was preferably below the 10mgKOH/g.The charging property of known vibrin and the pass of acid number are roughly proportional relation, and the negative charging of the high more then resin of acid number is big more, and be also influential to charged environmental characteristics simultaneously.That is, if the acid number height then under the low temperature and low humidity carried charge increase, hot and humid carried charge down reduces.Because because of the variation of the carried charge that environment caused, background is stained, the variation of image color, colorrendering quality increases, and is difficult to keep high quality image.In general, if acid number surpasses 20mgKOH/g, then might produce the increase of carried charge, the deterioration of environmental turbulence etc.
In the above-mentioned vibrin that uses among the present invention, controls such as the charging property that is had by aftermentioned resin strip controling agent, hydrophobicity monox, hydrophobic titanium oxide, resistance are as the resistance of toner particle.Therefore, if the acid number of vibrin surpasses 10mgKOH/g, then hinder the charged control effect of resin strip controling agent, hydrophobicity monox, hydrophobic titanium oxide.The acid number of the above-mentioned vibrin that uses among the present invention is preferably below the 10mgKOH/g, more preferably below the 5mgKOH/g.
The apparent viscosity that flow tester obtains of passing through of preferred above-mentioned vibrin reaches 10 3Temperature during Pas is 95~120 ℃.If said temperature is lower than 95 ℃, then the abundant intensity forfeiture of the heat penetration seal during photographic fixing if surpass 120 ℃, then might can not get sufficient gloss.Apparent viscosity reaches 10 3In the mensuration of the temperature of Pas, as flow tester, the CFT-500 type that for example uses Shimadzu Seisakusho Ltd. to make is at load 10kg/cm 2, aperture 1mm * long 1mm, programming rate measure viscosity down for 5 ℃/minute, reading apparent viscosity is 10 3The temperature of Pas.

Fig. 2 A, Fig. 2 B and Fig. 3 A~Fig. 3 C are the synoptic diagram of representing the toner shape for shape coefficient SF-1, shape coefficient SF-2 are described.Shape coefficient SF-1 represents the ratio of the circularity of toner shape, with following formula (1) expression.Be toner is projected on the two dimensional surface and the maximum length MXLNG of the shape that obtains square divided by graphics area AREA, multiply by 100 π/4 again and the value that obtains.
[mathematical expression 1]
SF-1={ (MXLNG) 2/ AREA} * (100 π/4) ... formula (1)
The value of above-mentioned SF-1 is 100 o'clock, toner be shaped as proper sphere, the value of SF-1 is big more then become more amorphous.
In addition, shape coefficient SF-2 represents the concavo-convex ratio of the shape of toner, with following formula (2) expression.Be with toner project to the figure that obtains on the two dimensional surface girth PERI square divided by graphics area AREA, multiply by 100 π/4 again and the value that obtains.
SF-2={ (PERI) 2/ AREA} * (100 π/4) ... formula (2)
The value of SF-2 is 100 o'clock, on toner surface, do not exist concavo-convex, the big more then toner surface of the value of SF-2 concavo-convex remarkable more.
If the shape subglobular of toner, then because toner approaches a contact with toner or toner with contacting of photoreceptor 1, and the absorption affinity between the toner dies down, therefore flowability raises, in addition, the absorption affinity of toner and photoreceptor 1 also dies down, transferring rate raises.On the other hand, spherical toner is owing to easily enter in the gap of cleaning balde 7a and photoreceptor 1, and the shape coefficient SF-1 or the SF-2 of toner can reach to a certain degree.In addition, if SF-1 and SF-2 increase, then toner disperses on image, and image quality reduces.Therefore, SF-1 and SF-2 preferably are no more than 180.
And, particularly, the mensuration of shape coefficient is following carries out: use scanning electron microscope (FE-SEMS-4800, Hitachi make) to take the photo of toner, this photo is imported in the image analysis apparatus (Luzex AP, Nireco Co. make) carry out analytical calculation.
In addition, in the present invention, use spindle shape and above-mentioned spindle shape to stipulate (wherein with major axis r1, minor axis r2, thickness r3, during r1 〉=r2 〉=r3), the ratio (r2/r1) of minor axis r2 and major axis r1 is 0.5~1.0 scope, thickness r3 and the ratio (r3/r2) of minor axis r2 is the toner of 0.7~1.0 scope, is preferred aspect colorrendering quality stable.
Fig. 3 A~Fig. 3 C is the synoptic diagram of the shape of this toner.Among Fig. 3 A, with major axis r1, minor axis r2, thickness r3 (wherein, during the roughly spherical toner of the regulation of r1 〉=r2 〉=r3), the ratio (r2/r1) (with reference to Fig. 3 B) of the preferred minor axis of toner of the present invention and major axis is 0.5~1.0, the ratio (r3/r2) (with reference to Fig. 3 C) of thickness and minor axis is 0.7~1.0 scope.The ratio (r2/r1) of minor axis and major axis because it is poor to depart from proper sphere shape, some repeatability and transfer efficiency, can not obtain high-quality image quality less than 0.5 o'clock.In addition, the ratio (r3/r2) of thickness and minor axis is less than 0.7 o'clock, near flat pattern, can not obtain the high transferring rate of spherical toner.Particularly thickness is 1.0 o'clock with the ratio (r3/r2) of minor axis, and forming major axis is the rotary body of turning axle, can improve the flowability of toner.
And r1, r2, r3 change the angle shot photo in the visual field by scanning electron microscope (SEM), observe and measure.
The preferred average circularity of above-mentioned toner is more than 0.94 and less than 1.00, more preferably 0.96~0.99.Average circularity is 0.94 when above, puts the repeatability excellence, from the uneven aspect of the colorrendering quality of the thin thread part that can reduce image, is preferred particularly.In addition, because transfer printing is also excellent, consider it is preferred from obtaining the high image quality aspect.In addition, when average circularity was high, toner was developed equably, transfer printing, in shadow tone portion, portion's toner forms piece and the situation of adhering to is few on the spot, was evenly distributed.Thus, toner lamination and when making colour superimposition, the few the same Neutral colour of inequality that can reproducing color therewith.Average circularity was less than 0.94 o'clock, and toner is to depart under the situation of spherical shape, is difficult to obtain the high quality images of sufficient transfer printing or free from dust.Unbodied particle like this is many to the contact point of flatness media such as photoreceptor, and charge concentration is in protruding top ends, so Van der Waals force or image force are compared the adhesion height with relatively more spherical particle.Therefore, in the static printing step, in the toner that amorphous particle and spheroidal particle mix, move to spherical particle selection, produce literal portion or line portion image and come off.In addition, for following development step, residual toner must be removed, and produces the unfavorable condition that needs cleaning device or toner yield (ratio of the toner that uses when image forms) to reduce.
In addition, the average circularity of toner is preferably below 30% less than the ratio of 0.93 toner particle.Above-mentioned ratio surpasses in the big toner of the deviation of 30% circularity, because charged speed, charged level broaden, carried charge distributes and also broadens, so not preferred.
The value that the average circularity of above-mentioned toner obtains for the girth of the equivalent circular that detects particle optically, equate divided by projected area.Specifically, use flow-type particle picture analytical equipment (FPIA-2000, Sysmex Corp. make) to measure.In the container of regulation, add the water that 100~150mL has removed impure solid matter in advance, add 0.1~0.5mL surfactant, add again and measure sample about 0.1~9.5g as spreading agent.The suspending liquid that is dispersed with sample is carried out about 1~3 minute dispersion treatment with ultrasonic disperser, and making dispersion liquid concentration is 3000~10000/μ L, shape and the distribution of measuring toner.

As mentioned above, the coefficient of static friction of this intermediate transfer body is preferably 0.1~0.6, more preferably 0.3~0.5.The volume resistance of this intermediate transfer body is preferably several Ω cm~10 3Ω cm.By making volume resistance is number Ω cm~10 3Ω cm can prevent that intermediate transfer body itself is charged, and the electric charge of giving by the electric charge member of imparting is difficult for remaining on this intermediate transfer body simultaneously, the transfer printing inequality in the time of therefore can preventing secondary transfer printing.Applying of transfer bias when in addition, carrying out secondary transfer printing easily.
The material of intermediate transfer body is not particularly limited, and can use material known.An one example is shown below.(1) material that yang type modulus (tensile modulus of elasticity) is high as the composite material of the composite material of PC (polycarbonate), the PVDF (Kynoar) of single belt, PAT (polyalkylene terephthalates), PC (polycarbonate)/PAT (polyalkylene terephthalates), ETFE (ethene-zellon multipolymer)/PC, ETFE/PAT, PC/PAT, be dispersed with the Thermocurable polyimide of carbon black etc.The deflection of single belt counter stress when image forms that these Young moduluss are high is few, particularly when forming coloured image, has the advantage that is difficult for producing misregister (mis-registration).(2) with the high band of above-mentioned Young modulus as basic unit, on its periphery, give superficial layer or middle layer and the band of 2~3-tier architecture of obtaining, the band of these 2~3-tier architectures has and can prevent because the performance that the centre of the line image that the hardness of single belt produces comes off.(3) the lower band of Young modulus that uses rubber and elastic body to obtain, the advantage that the centre that these bands produce line image hardly owing to its flexibility has comes off.In addition, prevent bending, therefore can need not reinforcement (rib) or anti-bending device, thereby can realize low cost because the width that makes band greater than driven roller with hang roller, utilizes from the elastic force of the ear of the outstanding band of roller.
Up to now, intermediate transfer belt has used fluorine-type resin, polycarbonate resin, polyimide resin etc., but has used all layers that will band in recent years or the part be with is made the elastic webbing of elastomeric element.Use the transfer printing of the coloured image of resin strip to have following problem.
Coloured image usually by four looks colour toners form.In a coloured image, form toner layer from one deck to four layer.Toner layer is under pressure by primary transfer (being transferred on the intermediate transfer belt from photoreceptor) or secondary transfer printing (being transferred on the paper (sheet) from middle transfer belt), and the cohesiveness between the toner raises.If the cohesiveness between the toner raises, the centre that then easily produces literal comes off or the phenomenon that comes off of portion's edge of image on the spot.Transfer printing resin strip hardness height can not be out of shape corresponding to toner layer, therefore, compresses toner layer easily, thereby is easy to generate the middle obscission of literal.
In addition, on various paper, form full-colour image recently, for example at Japan paper or the requirement of having a mind to form on the additional concavo-convex paper image improve.But the paper of flatness difference is easy and toner generation space when transfer printing, comes off thereby be easy to generate transfer printing.If improve the transfer pressure of secondary transfer printing portion in order to improve adaptation, then the condensing power of toner layer increases, and the centre that produces above-mentioned literal comes off.
Therefore, when being transferred on the paper, elastic webbing is used for following purpose.Elastic webbing is out of shape corresponding to the paper of toner layer, flatness difference in transfer printing portion.That is,, can exceedingly not improve transfer pressure, obtain good adaptation, can obtain not having the centre of literal to come off, even for the yet excellent transferred image of the paper homogeneity of planarity difference to toner layer owing to elastic webbing is followed local concavo-convex the distortion.
Resin as above-mentioned elastic webbing, be not particularly limited, can suitably select according to purpose, can enumerate for example polycarbonate, fluorine-type resin (ETFE, PVDF), polystyrene, chlorinated polyphenyl ethene, poly alpha methylstyrene, Styrene-Butadiene, styrene-vinyl chloride copolymer, styrene-vinyl acetate copolymer, styrene-maleic acid copolymer, copolymer in cinnamic acrylic ester (for example, styrene-propene acid methyl terpolymer, styrene-propene acetoacetic ester multipolymer, the styrene-propene butyl acrylate copolymer, misery ester copolymer of styrene-propene and styrene-propene acid phenylester multipolymer etc.), styrene-methacrylate copolymer (for example, styrene-methylmethacrylate copolymer, styrene-ethyl methacrylate copolymers, styrene-methacrylic acid phenylester multipolymer etc.), styrene-α-Lv Bingxisuanjiazhi multipolymer, styrene resins such as styrene-acrylonitrile-acrylate copolymer (homopolymer or the multipolymer that contain styrene or styrene substituent); Polymethyl methacrylate resin, the butyl methacrylate resin, the ethyl acrylate resin, the butyl acrylate resin, it is acrylic resin modified that (for example, silicone is acrylic resin modified, vestolit is acrylic resin modified, acrylic/polyurethane resin etc.), vestolit, styrene-vinyl acetate copolymer, vinyl chloride vinyl acetate copolymer, Abietyl modified maleic acid resin, phenolics, epoxy resin, vibrin, polyester polyurethane resin, tygon, polypropylene, polybutadiene, Vingon, ionomer resin, urethane resin, silicones, ketone resin, ethylene-ethyl acrylate copolymer, xylene resin, polyvinyl butyral resin, polyamide, modified polyphenylene ether resin etc.They can be used alone, and also can make up two or more uses.
As resilient material rubber or elastic body, can enumerate for example butyl rubber, fluorine class rubber, acrylic rubber, EPDM, NBR, acrylonitrile-butadiene-styrene (ABS) rubber natural rubber, isoprene rubber, styrene butadiene rubbers, butadiene rubber, ethylene-propylene rubber, the ethylene-propylene ter-polymers, chloroprene rubber, chlorosulfonated polyethylene, haloflex, urethane rubber, syndiotactic 1, the 2-polybutadiene, chloropropylene oxide class rubber, silicon rubber, fluororubber, thiokol, poly-norbornene rubber, hydrogenated nitrile rubber, thermoplastic elastomer (for example, polystyrene type, polyolefins, polyvinyl chloride, polyurethanes, polyamide-based, polyureas, polyesters, fluorine type resin) etc.They can be used alone, and also can make up two or more uses.
As the resistance value adjusting conductive agent, be not particularly limited, can suitably select according to purpose, for example can enumerate, the metal powder of carbon black, graphite, aluminium or nickel etc., tin oxide, titanium dioxide, antimony oxide, indium oxide, potassium titanate, antimony oxide-tin oxide composite oxides (ATO), indium oxide-tin oxide composite oxides conductive metal oxides such as (ITO), or on this conductive metal oxide, cover insulating fine particles such as barium sulphate, magnesium silicate, lime carbonate and conductive agent of obtaining etc.
Skin-material, top layer require to prevent pollution to photoreceptor by resilient material, and reduce the mantle friction resistance to the transfer belt surface, reduces the adhesion of toner, improves spatter property, thereby improve secondary transfer printing.For example, the material that can use one or more the combination that utilizes polyurethane, polyester, epoxy resin etc. to reduce surface energy and improve lubricity, for example with powder, the particle of one or more fluororesin, fluorine compounds, fluorocarbons, titania, silit etc., the powder of perhaps that particle diameter is different fluororesin, fluorine compounds, fluorocarbons, titania, silit etc., the combination of particle disperse to use.In addition, can also use such the passing through of fluorine class elastomeric material to heat-treat and form the layer of rich fluorine from the teeth outwards, thereby reduce the material of surface energy.
