(Application to toner)

Uses of the polymer according to the present invention include toners for electrostatic image development and application to an image forming process using the toners.

Specifically, the polymer can be used as a charge control agent that is internally or externally added to the toner. That is, the present invention is a charge control agent containing the polymer and a toner for developing electrostatic images containing the charge control agent.

The electrostatic charge image developing toner is used in the image forming method or image forming apparatus described below. The image forming method includes, for example, a charging step of uniformly charging the electrostatic latent image bearing member by applying a voltage to the charging member from the outside; A developing step of forming a toner image on the electrostatic latent image bearing member; A transfer step of transferring the toner image on the electrostatic latent image bearing member to the transfer material through or without an intermediate transfer member; And a heat fixing step of fixing the toner image on the transfer material under heating.

The image forming apparatus includes means corresponding to the processes of the method, that is, charging means, developing means, transfer means and heat fixing means, respectively.

Here, the description regarding the toner will be described.

Many electrophotographic methods using toner are known. The general method uses an electroconductive material to form an electrical latent image on an image bearing member (photosensitive member) by using various means; Developing the latent image with toner to form a visible image; Transferring the toner image onto a transfer material such as paper if necessary; Fixing the toner image onto the transfer material by heat and / or pressure or the like to obtain a copy.

As a method of visualizing an electric latent image, the cascade developing method, the magnetic brush developing method, the impression developing method, etc. are known. Using a magnetic toner and a rotating developing sleeve having a magnetic pole in the center; A method involving pulling a magnetic toner in a magnetic field from a place on a developing sleeve to a place on a photosensitive member is also used. The developing method used when developing the electrostatic latent image includes a two-component developing method including the use of a two-component developer composed of a toner and a carrier; And a one-component developing method using a one-component developer composed of only toners without using a carrier. Here, the colored fine particles generally referred to as a toner contain a binder resin and a coloring material as essential components, and other charge control agents, magnetic powders, and the like as necessary. The polymer according to the present invention can be used for such a toner.

By using, for example, a polymer compound represented by the formula (19) as a charge control agent used in the composition of the toner for electrostatic image development, excellent charging characteristics can be provided and excellent dispersibility of the compound in the toner resin And anti-spent properties.

In addition, when the polymer according to the present invention is used, it is possible to provide an electrostatic image developing toner which is prevented from generating an image blur upon output by the image forming apparatus and which is excellent in transferability.

Moreover, the charge control agent using the polymer according to the present invention can be colorless or weaken the coloring power. Therefore, it is possible to select any colorant in accordance with the color required for the color toner. Colorless or weakly colored charge control agents are preferred because they have little adverse effect on the original color of the dye or pigment.

In addition, when the toner for developing the electrostatic charge image is configured not to contain heavy metals, it is possible to provide a high safety and industrially useful toner.

(Charge As a control agent  use)

When the polymer according to the present invention is used as a charge control agent, as in the monomer unit represented by the above formula (19), the polymer preferably has a structure including a sulfonic acid group or a derivative of sulfonic acid group in the side chain.

The presence of units with anionic or electron withdrawing groups shows excellent negative chargeability.

The polymer according to the present invention has good compatibility with the binder resin of the toner.

The toner containing the polymer of the present invention has a high specific charge amount and a good stability over time. Therefore, even if the toner is stored for a long time, a clear image can be obtained stably in electrostatic image formation. In addition, the polymer is colorless or has a very weak color tone and has good negative chargeability. Therefore, black negatively charged toners and color toners can be produced, respectively. In addition, compatibility can be broadly controlled by appropriately selecting the type / composition ratio of the monomer units constituting the polymer of the present invention.

Here, if the resin composition is selected such that the charge control agent takes a microphase-separated structure in the toner binder, it is possible to stably maintain electric charge because no electrical continuity of the toner occurs.

In addition, the polymer of the present invention does not contain a heavy metal. Therefore, when the toner is produced by the suspension polymerization method or the emulsion polymerization method, the toner can be stably produced because there is no polymerization inhibitory effect by heavy metals that may be observed in the metal-containing charge control agent.

Here, the charge control agent will be described in more detail.

In order to impart a charge to the toner, the charging characteristics of the binder resin itself can be used without using a charge control agent. However, in this case, the stability and moisture resistance over time of charging may be inferior, and favorable image quality may not be obtained.

Therefore, a charge control agent is usually added for the purpose of charge retention and charge control of the toner. Examples of charge control agents conventionally known in the art today include charge control agents each having negative triboelectric chargeability, such as azo dye metal complexes, metal complexes of aromatic dicarboxylic acids, and metal complexes of salicylic acid derivatives; And a charge control agent such as nigrosine dye, triphenyl methane dye, and organic tin compound containing various quaternary ammonium salt dibutyltin oxide.

When the polymer according to the present invention is used as a charge control agent, the polymer may be used in combination with any of the above-mentioned conventionally known charge control agents.

As a conventionally known polymer charge control agent, for example, a copolymer of styrene and / or α-methylstyrene with an alkyl (meth) acrylate or alkyl (meth) acrylate amide having a sulfonic acid group (respectively, It is worth noting that 08-179564, Japanese Patent Application Laid-Open No. 08-012467, and Japanese Patent No. 2807795 are often used.

(By the present invention Polymer  Addition to toner)

In the present invention, as a method of incorporating the charge control agent made of any of the above-mentioned polymers into a toner, there are a method of embedding in a toner and a method of adding to a toner. The addition amount of the charge control agent in the case of internal addition is in the range of usually 0.1 to 50% by weight, preferably 0.2 to 20% by weight, based on the total weight of the toner binder and the charge control agent. Less than 0.1% by weight is not preferable because the degree of improvement in the chargeability of the toner may become insufficient. On the other hand, when the addition amount exceeds 50 weight%, it is unpreferable from an economic viewpoint. In addition, in the case of external addition, the weight ratio of the toner binder and the charge control agent is preferably in the range of 0.01 to 5% by weight based on the total weight of the toner binder and the charge control agent. It is desirable to attach yesterday. In addition, the polymer of the present invention may be used in combination with a conventionally known charge control agent. The amount of charge control agent other than the polymer of the present invention is not limited as long as the addition of the charge control agent can achieve the effect of using the polymer of the present invention, and the effect thereof is not impaired.

The number average molecular weight of the polymer of this invention used as a charge control agent is 1,000-1,000,000 normally, Preferably it is 1,000-300,000. At a number average molecular weight of less than 1,000, the polymer is completely compatible with the toner binder, making it difficult to form discontinuous domains, thereby providing a charge shortage and adversely affecting the flowability of the toner. In addition, the number average molecular weight over 1,000,000 makes it difficult to disperse the polymer in the toner.

The molecular weight of the polymer of the present invention was measured by GPC (gel permeation chromatography). A specific GPC measuring method is previously prepared by dissolving the polymer in 0.1 wt% LiBr-containing dimethyl formamide (DMF), chloroform and the like; Many samples are measured on the same mobile phase; Determining the molecular weight distribution from the calibration curve of the standard polystyrene resin.

Moreover, in this invention, the polymer in which the ratio (Mw / Mn) of the weight average molecular weight (Mw) and number average molecular weight (Mn) measured as mentioned above in the said polymer exists in the range of 1-10 is charged control agent. It is preferable to use as.

The polymers used as charge control agents in the present invention have a melting point of 20 to 150 ° C., in particular 40 to 150 ° C., or no melting point but a glass transition point of 10 to 150 ° C., in particular 20 to 150 ° C. desirable. If the polymer has a melting point of less than 20 ° C., or has a glass transition point of less than 10 ° C., it is likely to adversely affect the fluidity and storage stability of the toner. In addition, when the polymer has a melting point of more than 150 DEG C or a melting point but no glass transition point of more than 150 DEG C, it is difficult to knead the charge control agent in the toner, so that the charge amount distribution is increased. It is easy to become wide distribution. In this case, melting | fusing point Tm and glass transition point Tg can be measured using the differential scanning calorimeter of the high precision mid-heat input compensation type | mold, such as DSC-7 by a Perkin Elmer company, for example.

The composition of the toner for electrostatic image development of the present invention is usually from 0.1 to 50% by weight of the charge control agent, from 20 to 95% by weight of the toner binder, and from 0 to 15% by weight of the coloring material. The toner may contain 60% by weight or less of magnetic powder (for example, powder of ferromagnetic metal such as iron, cobalt or nickel, or a compound such as magnetite, hematite or ferrite), which also functions as a coloring material if necessary. have. The toner may contain various additives (such as lubricants (e.g., polytetrafluoroethylene, low molecular weight polyolefins, fatty acids, or metal salts or amides thereof)) and other charge control agents (e.g. metal-containing azo dyes and salicylic acid metal salts). And the like). In addition, in order to improve the fluidity of the toner, hydrophobic colloidal silica fine powder or the like may be used. The total amount of these additives is usually 10% by weight or less based on the toner weight.

In the toner of the present invention, it is preferable that at least a portion of the toner binder forms a continuous phase in one toner particle, and at least a portion of the charge control agent forms a discontinuous domain. Compared with the case where the charge control agent is completely used in the toner binder without forming discrete domains, the added charge control agent is more likely to be exposed on the surface of the toner, and the effect is expressed by a small amount of addition. Moreover, the dispersion particle diameter of the said domain becomes like this. Preferably it is 0.01-4 micrometers, More preferably, it is 0.05-2 micrometers. If the particle diameter of dispersion exceeds 4 mu m, the dispersibility is insufficient, the charge amount distribution is widened, and the transparency of the toner is deteriorated. In addition, when the dispersed particle diameter is less than 0.01 mu m, addition of a large amount of charge control agent is necessary, as in the case where it is completely compatible with the toner binder without forming discrete domains. The fact that at least part of the charge control agent forms discrete domains and the dispersed particle diameter of the domain can be confirmed by observing the fragments of the toner by a transmission electron microscope or the like. In order to clearly observe the interface, the toner fragments may be dyed with ruthenium tetraoxide, osmium tetraoxide, or the like, and then observed by an electron microscope.

In addition, for the purpose of reducing the particle size of the discontinuous domains formed by the polymer of the present invention, a polymer compatible with the toner binder and compatible with the toner binder may also be blended as a compatibilizer. Examples of the compatibilizer include at least 50 mol% of a polymer chain containing at least 50 mol% of monomers having substantially the same structure as the constituent monomers of the polymer of the present invention, and at least 50 mol% of monomers having substantially the same structure as the constituent monomers of the toner binder. The polymer chain comprises the polymer to be bonded in a graft or block manner. The amount of the compatibilizer used is usually 30% by weight or less, preferably 1 to 10% by weight, based on the polymer of the present invention.

Examples of the magnetic material used at this time include iron oxides such as magnetite, hematite and ferrite; Metals such as iron, cobalt, nickel or other metals such as aluminum, cobalt, copper, lead, magnesium, tin, zinc, antimony, beryllium, bismuth, cadmium, calcium, manganese, selenium, titanium, tungsten, vanadium Alloys and mixtures thereof. As the magnetic material which can be used in the present invention, the average particle size is preferably 2 μm or less, more preferably about 0.1 to about 0.5 μm. The amount of the magnetic material in the toner is preferably 20 to 200 parts by weight, particularly preferably 40 to 150 parts by weight based on 100 parts by weight of the binder resin.

Further, in order to achieve higher image quality, it is necessary to make it possible to faithfully develop a finer latent image dot. For this purpose, for example, the weight average particle size of the electrostatic charge image developing toner particles of the present invention is preferably adjusted to be within the range of 4 to 9 mu m. That is, in the toner particles having a weight average particle size of less than 4 mu m, the transfer efficiency is lowered, and the amount of transfer residual toner remaining on the photosensitive member tends to increase, which is likely to cause unevenness of the image due to blur and transfer failure. Therefore, it is not preferable. In addition, when the weight average particle size of the toner particles exceeds 9 µm, scattering is likely to occur around characters or line images.

In the present invention, the average particle size and particle size distribution of the toner are a Coulter Counter TA-II type or Coulter Multisizer (Beckman) equipped with an interface (product of Nikkaki Bios Co., Ltd.) and a personal computer for outputting the number distribution and the volume distribution. Coulter, Inc.) was measured. As electrolyte solution used for this measurement, 1% NaCl aqueous solution is manufactured using primary sodium chloride. For example, commercially available ISOTON R-II (manufactured by Coulter Scientific Japan) can be used as the electrolyte. The specific measuring method is as follows. 0.1 to 5 ml of a surfactant (preferably alkylbenzenesulfonate) as a dispersant is added to 100 to 150 ml of the electrolyte. A sample for measurement is prepared by adding 2 to 20 mg of measurement sample. At the time of measurement, the electrolyte solution in which the measurement sample is suspended is dispersed for about 1 to 3 minutes using an ultrasonic dispersion machine, and then the volume of the toner having a particle size of 2 μm or more by the Coulter Counter TA-II using a 100 μm aperture. The volume distribution and the number distribution were calculated by measuring the and number. Subsequently, the weight average particle size (D4) and the length average particle size (D1) of the number basis were calculated from the volume distribution and the number distribution according to the present invention, respectively.

(Charge amount)

In the electrostatic charge image developing toner of the present invention, the charge amount (two-component method) per unit weight is -10 to -80 mu C / g, more preferably -15 to -70 mu C / g. It is preferable to increase the transfer efficiency in the transfer method including the use.

The measuring method of the charge quantity (two component triboelectricity) by the two-component method used in this invention is as showing below. The electric charge measuring device shown in Fig. 7 was used for the measurement. First, under a constant environment, a mixture obtained by adding 0.5 g of the toner to be measured to 9.5 g of this carrier is added to a polyethylene bottle of 50 to 100 ml capacity using EFV 200/300 (manufactured by Powdertech) as a carrier. This bottle is placed in a shaker with a constant amplitude and shaken for a predetermined time under shaking conditions of an amplitude of 100 mm and a shaking speed of 100 strokes / minute.

Subsequently, 1.0-1.2 g of the mixture was placed in a metal measuring container 42 having a 500 mesh network 43 at the bottom of the charge amount measuring device 41 shown in FIG. Cover. The total weight of the measuring vessel 42 at this time is weighed and denoted by W1 (g). Next, the toner in the container is sucked through the suction port 47 by an aspirator (not shown) (at least the portion of the aspirator in contact with the measuring vessel 42 is made of an insulator), while the airflow control valve 46 is adjusted. The pressure of the vacuum gauge 45 is set to 2,450 kPa (250 mmAq). In this state, suction is performed for 1 minute to remove the toner by suction. The read result of the electrometer 49 at this time is represented by V (volts). Here, 48 is a capacitor having a capacitance C (µF). In addition, the total weight of the measuring apparatus after suction is measured and represented by W2 (g). Then, the triboelectric charge amount (μC / g) of the toner is calculated from these measured values according to the following equation:

Triboelectric charge (μC / g) = C x V / (W1-W2).

(Molecular Weight Distribution of Binder Resin)

The binder resin used as a constituent material of the electrostatic charge image developing toner of the present invention preferably has a peak in the low molecular weight region in the range of 3,000 to 15,000 in the molecular weight distribution by GPC, especially when produced by the grinding method. In other words, if the GPC peak in the low molecular weight region exceeds 15,000, the improvement of the transfer efficiency may be insufficient. If a binder resin having a GPC peak of less than 3,000 in the low molecular weight region is used, fusion is more likely to occur during surface treatment, which is not preferable.

In the present invention, the molecular weight of the binder resin was measured by GPC (gel permeation chromatography). A specific GPC measurement method uses a sample obtained by extracting a toner for 20 hours using a Soxhlet extractor with a THF (tetrahydrofuran) solvent; A-801, 802, 803, 804, 805, 806, and 807 (manufactured by Showa Denko Corporation) are connected to form a column; The molecular weight distribution is measured by using a green calibration curve using a standard polystyrene resin. Moreover, in this invention, it is preferable to use binder resin in which ratio (Mw / Mn) of the weight average molecular weight (Mw) and number average molecular weight (Mn) measured in this way exists in the range of 2-100.

In addition, the toner of the present invention is preferably prepared so that the glass transition point Tg is 40 ° C to 75 ° C, more preferably 52 ° C to 70 ° C from the viewpoint of fixability and shelf life by using a suitable material. In this case, the glass transition point Tg can be measured using a differential scanning calorimeter of a high precision heat-resistant input compensation type such as DSC-7 manufactured by Perkin Elmer. In addition, the measuring method is performed according to ASTMD 3418-82. In the present invention, when measuring the glass transition point Tg, the temperature of the sample to be measured is raised once to remove the entire history; Quench the sample; Again, it is recommended to use the DSC curve measured by raising the temperature of the sample at a temperature rising rate of 10 ° C / min in a temperature range of 0 to 200 ° C.
