On the other hand, four photoconductor drums 11 are respectively towards diagram revolution clockwise.And, the surface of photoconductor drum 11 with the subtend position homogeneous of charging roller 12a (charging part 12) charged (charging operation).Like this, on photoconductor drum 11, form charged potential.After this, charged photoconductor drum 11 surfaces arrive laser irradiating position.
At write section 6,, penetrate the laser corresponding with picture signal from light source with of all kinds corresponding.Diagram is omitted, and laser sees through a plurality of lens after inciding the polygonal mirror reflection.Through the of all kinds composition of the laser behind a plurality of lens, through different light paths (exposure process) by yellow, magenta, cyan, black.
The laser radiation corresponding with yellow composition is on photoconductor drum 11 surfaces from paper left side first cartridge processing 10Y.At this moment, the laser of yellow composition is because of revolving shaft direction (main scanning direction) scanning of the polygonal mirror of high speed rotary (not having diagram) along photoconductor drum 11.Like this, on by the photoconductor drum 11 after the charging roller 12a charging, form the electrostatic latent image corresponding with yellow composition.
Equally, the laser radiation of cyan composition forms the electrostatic latent image of cyan composition on photoconductor drum 11 surfaces from second the cartridge processing 10C in paper left side.The laser radiation corresponding with the magenta composition forms the electrostatic latent image corresponding with the magenta composition on photoconductor drum 11 surfaces from the 3rd the cartridge processing 10M in paper left side.The laser radiation of black composition is at (black use imaging portion) photoconductor drum 11 surfaces of the 4th from paper left side (moving direction of intermediate transfer belt 17 downstream) relatively cartridge processing 10BK, the electrostatic latent image of formation black composition.
After this, photoconductor drum 11 surfaces that form electrostatic latent image of all kinds arrive the subtend position with development section 13 respectively.And, to photoconductor drum 11, make image development (developing procedure) on the photoconductor drum 11 from each development section 13 toner supply of all kinds.
After this, 11 surfaces of the photoconductor drum behind the developing procedure arrive the subtend position with intermediate transfer belt 17 respectively.At this, in subtend position separately, primary transfer roller 14 is set, join with intermediate transfer belt 17 inner peripheral surfaces.Then, in primary transfer roller 14 positions, be formed on that each colour toners picture order of photoconductor drum 11 is superimposed to be transferred to (first transfer printing process) on the intermediate transfer belt 17.
Then, photoconductor drum 11 surfaces behind first transfer printing process arrive the 15 subtend positions with cleaning portion respectively.And in cleaning portion 15, the not transfer printing toner that remains on the photoconductor drum 11 is recovered (cleaning process).
After this, photoconductor drum 11 surface orders finish a series of imaging processing of photoconductor drum 11 through the position of feeding lubricating device 16 and the position of the electric portion that disappears (not having diagram).
On the other hand, move according to the diagram direction of arrow on intermediate transfer belt 17 surfaces of image congruencing transfer printing of all kinds on the photoconductor drum 11, arrives secondary transfer roller 18 positions.And in secondary transfer roller 18 positions, the coloured image secondary transfer printing on the intermediate transfer belt 17 is (second transfer printing process) on recording medium P.
After this, intermediate transfer belt 17 surfaces arrive the position of intermediate transfer belt cleaning portion (not having diagram).Then, the not transfer printing toner on the intermediate transfer belt 17 is recovered to intermediate transfer belt cleaning portion, finishes a series of transfer process on the intermediate transfer belt 17.
At this, via transporting guide, transport by registration roller 19 grades from sheet feed section 7 for the recording medium P of secondary transfer roller 18 positions.
At length say, supply with transfer paper P by paper feed roller 8, after transporting guide, be directed to registration roller 19 from the sheet feed section 7 of taking in recording medium P.Make that the recording medium P that arrives registration roller 19 is consistent as the time with the toner on the intermediate transfer belt 17, transport towards secondary transfer roller 18 positions.
After this, transfer printing chromatic colour record images medium P is directed to photographic fixing portion 20.In photographic fixing portion 20, at the clamping part of fixing roller and backer roll, the coloured image photographic fixing is on recording medium P.
Then, the recording medium P after the photographic fixing operation piles up in row's paper portion 5 after being discharged to outside the device body 1 by exit roller 29 as output image, finishes a series of image and forms processing.
Below, with reference to Fig. 2, specify the imaging portion that image forms device.
Fig. 2 is that expression is as the pie graph of black with the cartridge processing 10Bk (black and white is used cartridge processing) of imaging portion.Black and white is made up of roughly the same component parts with cartridge processing 10Bk and colored different except the look of the toner that is used for imaging process with cartridge processing 10Y, 10M, 10C, therefore, and colored diagram and the suitable omission of explanation with cartridge processing 10Y, 10M, 10C.
As shown in Figure 2; In cartridge processing 10Y, 10M, 10C, 10BK; Carry the photoconductor drum 11 put body as picture, make the charging part 12 (charging roller) that photoconductor drum 11 is charged, make the development section 13 that is formed on the latent electrostatic image developing on the photoconductor drum 11; Reclaim on the photoconductor drum 11 the not cleaning portion 15 of transfer printing toner, the feeding lubricating device 16 of supply of lubricant is accommodated in the housing integratedly on photoconductor drum 11.
At this, carrying the photoconductor drum 11 of putting body as picture is Organophotoreceptors of electronegative property, on drum type electric conductivity supporting mass, is provided with photographic layer etc.
Diagram is omitted, photoconductor drum 11 on as the electric conductivity supporting mass of basic unit the order lamination as the following coating of insulation course, as the charge generating layer and the charge transport layer of photographic layer, protective seam (superficial layer).
Electric conductivity supporting mass (basic unit) as photoconductor drum 11 can use volume resistance 10
10Conductive material below the Ω cm.
Charging part 12 (charging roller) is the roller member of the elastic layer of resistance in the periphery of conductive metal core coats, feeding lubricating device 16 relatively, be provided in photoconductor drum 11 along the gyratory directions downstream.Again, charging part 12 (charging roller) relatively photoconductor drum 11 set to subtend non-contactly, so that the non-cohesive lubricant that supplies to photoconductor drum 11 by feeding lubricating device 16.
And, never illustrated power supply unit to charging part 12 apply fixed voltage, thus, make that photoconductor drum 11 uniform surface of subtend are charged.
Development section (developing apparatus) 13 mainly by with the developer roll 13a of photoconductor drum 11 subtends; Transport spiral 13b1 with first of developer roll 13a subtend; Transport second of spiral 13b1 subtend through partition member and first and transport spiral 1362, with the scraper plate 13c formation of developer roll 13a subtend.Developer roll 13a is by being fixedly installed on inside, forming the magnet of magnetic pole at the roller side face, and rotating cover constitutes around the magnet.Upward form a plurality of magnetic poles by magnet at developer roll 13a (cover), upload at developer roll 13a and put developer.
In development section 13, take in the two-component developing agent that constitutes by carrier and toner.
In order to improve image quality, it is the spherical toner more than 0.98 that toner uses circularity." circularity " is the average circularity that is detected by flow formula particle image analytical equipment " FPIA-2000 " (East Asia medical electric corporate system).Specifically, in container, have the water 100-150ml that removes the impurity solid content in advance, in this container, add surfactant (preferred alkyl benzene sulfonate) 0.1-0.5ml, add again and measure about test portion (toner) 0.1-0.5g as spreading agent.After this, with the about 1-3 of suspending liquid minute the dispersion treatment that ultrasonic disperser disperses this toner, be that 3000-10000/μ l person is arranged on above-mentioned analytical equipment with dispersion liquid concentration, measure toner shape and distribution.
As spherical toner, the toner (crushed toner) of the abnormity that can distort for the shape that the comminuting method that extensively adopted forms in the past carries out heat treated etc. makes its spheroidization, perhaps also can be through the polymerization manufacturing etc.
Use this spherical toner occasion, in the past, take place sometimes to get in the tolerances between cleaning balde 15a and the photoconductor drum 11, push through this gap, it is bad to produce cleaning.But, in this example, through feeding lubricating device 16 with lubricant applying on photoconductor drum 11 surfaces, improve toner fissility (removing property) on the photoconductor drum 11, therefore, can suppress generation and clean bad.
Feeding lubricating device 16 is by solid shape lubricant 16b; Reach the lubricant donor rollers 16a (brush shape roller) that solid shape lubricant 16b slips with photoconductor drum 11; The holding member 16c that keeps solid shape lubricant 16b; The housing 16f that holding member 16c and solid shape lubricant 16b are taken in together; With pivoting part 16g and the extension spring 16h (pressing mechanism) that solid shape lubricant 16b energizes towards lubricant donor rollers 16a with holding member 16c, make and scrape formation such as tabular parts 16d through what lubricant donor rollers 16a supplied to lubricant thin layerization on the photoconductor drum 11.Scrape the relative lubricant donor rollers of tabular parts 16d 16a, in the position, gyratory directions downstream of photoconductor drum 11, photoconductor drum 11 joins with reverse relatively.
On photoconductor drum 11, supply with the lubricant of thin layerization through the feeding lubricating device 16 of such formation.About the formation and the action of feeding lubricating device 16, will specify at the back literary composition.
With reference to Fig. 2 further explain imaging processing recited above.
And frictional electrification is adsorbed on the toner on the carrier, carries with carrier and puts on developer roll 13a.Carry the developer put on developer roll 13a and after this arrive the position of scraper plate 13c.Then, the developer on the developer roll 13a arrives the subtend position (developing regional) with photoconductor drum 11 after the position of scraper plate 13c is adjusted in right amount.
After this, in developing regional, the toner in the developer is attached on the electrostatic latent image that is formed on photoconductor drum 11 surfaces.Say that at length form electric field by the sub-image current potential (exposure current potential) of the image portion of irradiating laser L and the potential difference (PD) (development current potential) that is applied between the development bias voltage of developer roll 13a, toner is attached on the sub-image and (forms the toner picture).
After this, the toner that is attached to photoconductor drum 11 at developing procedure almost all is transferred on the intermediate transfer belt 17.And the not transfer printing toner that remains on the photoconductor drum 11 is recovered in the cleaning portion 15 by cleaning balde 15a.
At this, diagram is omitted, and the toner replenishing portion that is located at device body 1 is by changing the ampuliform toner container 28 that constitutes freely, and maintenance/driving toner container 28 turns round, the toner hopper portion to the new toner of development section 13 supplies constitutes simultaneously.In toner container 28, take in new toner (a certain among yellow, magenta, cyan, the black) again.At the inner peripheral surface of toner container 28 (toner bottle), form the spiral fashion projection again.
Along with the consumption of the toner in the development section 13 (existing toner), the new toner in the toner container 28 is from the suitably supply in development section 13 of toner replenishing mouth.Diagram is omitted, the toner consumption in the development section 13 by with the reflective photoelectric sensor of photoconductor drum 11 subtends, and be arranged on the Magnetic Sensor that second of development section 13 transports spiral 13b2 below and detect indirectly or directly.
Specify the formation and the action of the feeding lubricating device 16 (lubricant supply unit) of this example below.
As shown in Figure 2; Feeding lubricating device 16 is by solid shape lubricant 16b; The periphery that slips with photoconductor drum 11 and solid shape lubricant 16b is provided with the lubricant donor rollers 16a (brush shape roller) of bristle; The holding member 16c that keeps solid shape lubricant 16b; The housing 16f that holding member 16c and solid shape lubricant 16b are taken in together with pivoting part 16g and the extension spring 16h (pressing mechanism) that solid shape lubricant 16b energizes towards lubricant donor rollers 16a with holding member 16c, makes the plate-shaped member 16d formations such as (thin layer plates) that supplies to the lubricant thin layerization on the photoconductor drum 11 through lubricant donor rollers 16a.
If bristle lengths surpasses 20mm, then through wiping with the sliding repeatedly of photoconductor drum 11 between long-term, bristle towards decide direction mao, Gu the scraping getting property and remove the reduction of toner property of shape lubricant 16b from photoconductor drum 11.In contrast, if the not enough 0.2mm of bristle lengths, then the phase relay of the physics of shape lubricant 16b and photoconductor drum 11 is not enough relatively admittedly.Therefore, be preferably, bristle lengths is in above-mentioned scope.
The relative Fig. 2 of lubricant donor rollers 16a court is rotating photoconductor drum 11 clockwise, with reverse contact revolution (revolution clockwise of Fig. 2).Again; Lubricant donor rollers 16a (bristle) is configured to slip with solid shape lubricant 16b and photoconductor drum 11; Lubricant donor rollers 16a scrapes from solid shape lubricant 16b through revolution and gets lubricant; With this scrape the lubricant of getting be transported to photoconductor drum 11 slip the position after, with this lubricant applying on photoconductor drum 11.
Back quadrate part at solid shape lubricant 16b; Irregular in order to eliminate lubricant donor rollers 16a with contacting of solid shape lubricant 16b; Configuration pressing mechanism 16g, 16h makes to keep (bonding) to energize towards lubricant donor rollers 16a at the solid shape lubricant 16b of holding member 16c state.At this, pressing mechanism is by a pair of pivoting part 16g that is bearing in holding member 16c pivotally, and the energize extension spring 16h of parts of the conduct that is connected with a pair of pivoting part 16g constitutes, and will specify at the back literary composition about this structure.
In this example, mainly form solid shape lubricant 16b by zinc stearate.At length say,, too apply and be free from side effects to have sufficient lubricity Gu the dissolving of shape lubricant 16b system is the lubricant additive of main composition with zinc stearate, very suitable.
Zinc stearate is typical layered crystal.Laminated crystalline has the layer structure of amphipathic molecule self-organization, if apply shearing force, crystal is prone to split and slide along interlayer.Therefore, can make photoconductor drum 11 surperficial low-friction coefficientizations.That is,, can cover photoconductor drum 11 surfaces effectively through minor amounts of lubricants owing to receive the layered crystal that shearing force covers photoconductor drum 11 surfaces equably.
As solid shape lubricant 16b, except zinc stearate, can also use barium stearate, ferric stearate, nickel stearate, cobaltous octadecanate, copper stearate, strontium stearate, calcium stearate etc. have the material of stearic acid-base.Again, also can use identical fatty acid-based zinc oleate, barium oleate, plumbi oleas, zinc palmitate, palmitic acid barium, palm lead plumbate.In addition, as fatty acid-based, it is sad to use, leukotrienes etc.Have again, also can use candelilla wax, Brazil wax, rice wax, haze tallow, big leaf oil, close wax, waxes such as sheep oil.Above-mentioned substance is prone to become the solid shape lubricant of organic system, and is good with the compatibility of toner.
Be coated on photoconductor drum 11 surfaces if will consolidate shape lubricant 16b through lubricant donor rollers 16a; The lubricant applying of powder shaped is on photoconductor drum 11 surfaces; But lubricity can not be given full play under this state; Therefore, scraping tabular parts 16d (thin layer scraper plate) plays as making lubricant homogenization functions of components.Scrape tabular parts 16d through this, on photoconductor drum 11, carry out the membranization of lubricant, greasy property is given full play to its lubricity.
At this moment, the lubricant of the powder shaped through lubricant donor rollers 16a coating is a micropowder, through scrape tabular parts 16d with the molecular film level in photoconductor drum 11 upper filmizations.
Below, be described in detail in the formation/action of the feeding lubricating device 16 that has characteristic in this example.
With reference to Fig. 3, in the feeding lubricating device 16 of this example, Gu the bonding holding member 16c that remains on of shape lubricant 16b.Specifically, between holding member 16c and solid shape lubricant 16b, being situated between has double sticky tape or bonding agent etc., the solid shape lubricant 16b of the bonding maintenance of holding member 16c.At this, holding member 16c is the sheet metal that bending machining becomes " コ " word shape, is formed for keeping a plurality of hole 16c2 of portion (bearing portion) of pivoting part 16g in its two sides.
At this, with reference to Fig. 3, Fig. 4, Fig. 6 etc. at holding member 16c, along the separation point position of Width (the paper vertical direction of Fig. 2, the left and right directions of Fig. 6), support a pair of pivoting part 16g (push part) respectively pivotally.This a pair of pivoting part 16g turns round towards deciding direction respectively because of the power of energizing that extension spring 16h (parts of energizing) causes, pushes solid shape lubricant 16b indirectly through holding member 16c, feasible shape lubricant 16b and lubricant donor rollers 16a crimping admittedly.
Say that at length with reference to Fig. 4, Fig. 5 in the two sides of pivoting part 16g, becomes the fulcrum 16g1 (axial region) of the centre of gyration.And the fulcrum 16g1 of this pivoting part 16g inserts the 16c2 of hole portion of holding member 16c, and pivoting part 16g remains on holding member 16c pivotally.Like Fig. 3 and shown in Figure 6, two pivoting part 16g are separately positioned on holding member 16c, become left-right symmetric at Width.
Again, with reference to Fig. 3, the extension spring 16h that Fig. 6 etc., a pair of pivoting part 16g are used as the parts of energizing connects.Say that at length the hook portion at the two ends of extension spring 16h is connected with the 16g4 of hole portion of pivoting part 16g (can with reference to Fig. 4) respectively.
And this extension spring 16h has as the functions of components of energizing, and makes a pair of pivoting part 16g towards different mutually direction revolutions, so as with housing 16f crimping, make holding member 16c towards energizing near the direction of lubricant donor rollers 16a.Specifically, extension spring 16h (parts of energizing) makes a pair of pivoting part 16g revolution, makes the span of the 16g2 of cam face portion between partly of a pair of pivoting part 16g and housing 16f crimping reduce gradually.
That is, the 16g2 of cam face portion (can with reference to Fig. 4 etc.) joins with the internal face of housing 16f, and two pivoting part 16g receive the spring force (power of energizing) of the above-mentioned cam face 16g2 of portion direction near each other from extension spring 16h.Thus, the pivoting part 16g of the left of Fig. 6 is energized, make its with fulcrum 16g1 as the centre of gyration, towards the revolution of the counterclockwise of Fig. 6.In contrast, right-hand pivoting part 16g of Fig. 6 is energized, make its with fulcrum 16g1 as the centre of gyration, towards the revolution clockwise of Fig. 6.
In more detail; Shown in Fig. 6 (A)-(B), along with the increase of the Cumulative Elapsed Time of image processing system 1, Gu shape lubricant 16b is because of to lubricant donor rollers 16a supply of lubricant; Be consumed its thickness (to the thickness of the crimping direction of lubricant donor rollers 16a) attenuation gradually.And a pair of pivoting part 16g is respectively along with the above-mentioned consumption (thin-walled property) of shape lubricant 16b admittedly, because of the power of energizing of extension spring 16h is turned round towards above-mentioned direction.
In other words; The 16g2 of cam face portion that is formed on a pair of pivoting part 16g is respectively along with the consumption of shape lubricant 16b admittedly; Because of the power of energizing that extension spring 16h causes is turned round; With housing 16f crimping, make holding member 16c move towards direction near lubricant donor rollers 16a with solid shape lubricant 16b.
Like this; When a pair of pivoting part 16g turns round; Along with its revolution (Gu consumption of shape lubricant 16b); Angle by the formed gyratory directions of imaginary line of the mobile crimping direction of the imaginary line segment that connects position (application point) that pivoting part 16g (16g2 of cam face portion) and housing 16f join and fulcrum 16g1 (fulcrum) and holding member 16c (Gu shape lubricant 16b) reduces gradually.Again; Along with revolution (Gu consumption of shape lubricant 16b); The angle of the formed gyratory directions of imaginary line of the direction of energizing of the power of energizing effect of imaginary line segment and extension spring 16h of position (force) and fulcrum 16g1 (fulcrum) of pivoting part 16g that is received the power of energizing of extension spring 16h by connection increases gradually.
Below, with reference to Fig. 6 (A)-(B), specify along with the action of the pivoting part 16g of the consumption (thin-walled property) of shape lubricant 16b admittedly).
At first; Shown in Fig. 6 (A); If (bonding/remain on the state of holding member 16c) is set to feeding lubricating device 16 (device body 1) the solid shape lubricant 16b of new product state, then becomes under the longest state in the span of the 16g2 of cam face portion of a pair of pivoting part 16g (with the distance of two pressure contact portions Width each other of housing 16f), because of holding member 16c (pressing mechanism 16g; 16h), Gu shape lubricant 16b and lubricant donor rollers 16a crimping.And under this state, (lubricant donor rollers 16a) begins to photoconductor drum 11 supply of lubricant by feeding lubricating device 16.The 16c2 of hole portion is made as slotted hole, makes that fulcrum 16g1 can slippage, and also can be constructed such that the end face of inside of the 16g3 of pushing portion (can with reference to Fig. 4) the pushing holding member 16c of pivoting part 16g.
After this, shown in Fig. 6 (B), along with effluxion; Along with by the progress of feeding lubricating device 16 (lubricant donor rollers 16a) to photoconductor drum 11 supply of lubricant; The span of the 16g2 of cam face portion of a pair of pivoting part 16g reduces gradually, under this state, because of holding member 16c (pressing mechanism 16g; 16h), Gu shape lubricant 16b and lubricant donor rollers 16a crimping.
Then; At last; Diagram is omitted, and along with by the further progress of feeding lubricating device 16 (lubricant donor rollers 16a) to photoconductor drum 11 supply of lubricant, becomes under the minimum state at the wall thickness of consolidating shape lubricant 16b; Take out solid shape lubricant 16b and holding member 16c from feeding lubricating device 16 (device body 1), carry out the replacing maintaining of solid shape lubricant 16b.The consumption of the solid shape lubricant 16b of the direct or indirect detection of detection means (for example; The means that the Cumulative Elapsed Time of feeding lubricating device 16 is counted; The perhaps means of the thickness of the solid shape lubricant 16b of optical detection etc.); Carry out the testing result of the period of the replacing maintaining of shape lubricant 16b admittedly, judge according to above-mentioned detection means.
At this; With reference to Fig. 5; Fig. 6; At the feeding lubricating device 16 of this example, be located at housing 16f (each settings of relative two pivoting part 16g) as the convex shaped part 16f10 of guide part, the direction generating plane that restriction pivoting part 16g intersects towards rotating relatively imaginary plane (face parallel with the paper of Fig. 4) is.
Say that at length with reference to Fig. 5, convex shaped part 16f10 (guide part) forms convex, the crimping face 16f1 of housing 16f that makes the relative crimping of pivoting part 16g, outstanding towards direction near solid shape lubricant 16b.Again, in this example, convex shaped part 16f10 forms respectively and pivoting part 16g two sides subtend, clips pivoting part 16g.Like this, through convex shaped part 16f10 (guide part) is set at housing 16f, pivoting part 16g revolution is led by convex shaped part 16f10.
Through this formation, during starting etc.,, also can suppress the undesirable condition that pivoting part 16g face falls really even solid shape lubricant 16b receives big counter-force of moment from lubricant donor rollers 16a at lubricant donor rollers 16a from halted state to the beginning driving rotational.In other words; Can prevent the pivoting part 16g variable phenomenon (from of the variation of Fig. 7 (A) state) of shape lubricant 16b inclination crimping ground posture relatively admittedly to Fig. 7 (B1) state, or the variable phenomenon (from the variation of Fig. 7 (A) state to Fig. 7 (B2) state) of the solid relative lubricant donor rollers with pivoting part 16g of shape lubricant 16b 16a inclination crimping ground posture.
Promptly; Even pivoting part 16g will fall by generating plane; Because pivoting part 16g contacts with convex shaped part 16f10 (guide part), therefore, can not fall by generating plane; Keep the pivoting part 16g posture of shape lubricant 16b relatively admittedly, Gu the posture of the relative lubricant donor rollers of shape lubricant 16b 16a (keeping Fig. 7 (A) state).Therefore; That can suppress that biasing contact because of the solid relative lubricant donor rollers of shape lubricant 16b 16a causes scrapes the lubricant heterogeneity on the lubricant donor rollers 16a that gets from shape lubricant 16b admittedly; Inhibition also becomes heterogeneity by the lubricant that feeding lubricating device 16 (lubricant donor rollers 16a) supplies on the photoconductor drum 11, suppresses local and the damaged of cleaning balde 15a is taken place or clean bad etc. undesirable condition.
At this, in this example, the difference subtend forms the convex shaped part 16f10 as guide part in the two sides of pivoting part 16g, clips pivoting part 16g.
In contrast; Shown in Fig. 8 (A); Among the two sides of pivoting part 16g (face parallel with the paper of Fig. 4 is provided with the face of fulcrum 16g1), also can only form convex shaped part 16f10 as guide part at the side corresponding with the gyratory directions upstream side of lubricant donor rollers 16a.That is, shown in Fig. 8 (A), form a convex shaped part 16f10, with side, the right side subtend of pivoting part 16g.Even in this occasion; As above-mentioned for Fig. 7 illustrated; The direction that pivoting part 16g face falls roughly can be confirmed as the corresponding side of gyratory directions upstream side with lubricant donor rollers 16a; Therefore, identical with this example, the effect that the face of the pivoting part 16g that can fully be inhibited falls.
Have again, shown in Fig. 8 (B), also can be with being connected together as the convex shaped part 16f10 of guide part and the sidewall 16f2 of housing 16f.That is, shown in Fig. 8 (B), make that the sidewall 16f2 of convex shaped part 16f10 and housing 16f is integrated, its length extends to the position of sidewall 16f2.Thus, the intensity of force that convex shaped part 16f10 receives from pivoting part 16g relatively becomes big, when inhibition pivoting part 16g face falls, can prevent the undesirable condition that pivoting part 16g is damaged really.
Have, in this example, use convex shaped part 16f10 as guide part, it is formed on the outstanding with the internal face (bottom surface) on the one side with crimping face 16f1 of housing 16f relatively.
In contrast, also can be shown in Fig. 9 (A), the side wall surface 16f15a that uses slot part 16f15 is as guide part, and the crimping face 16f1 of the housing 16f of pivoting part 16g crimping is arranged with towards the direction of leaving solid shape lubricant 16b, forms above-mentioned slot part 16f15.Promptly; Shown in Fig. 9 (A); With the crimping face 16f1 of the pivoting part 16g of housing 16f crimping bottom surface for the slot part 16f15 that is formed on internal face (bottom surface); The two side walls 16f15a of slot part 16f15 has the function as guide part, its respectively with the two sides subtend of pivoting part 16g, clip pivoting part 16g.Even in this occasion, also identical with this example, the effect that the pivoting part 16g face that can be inhibited falls.Especially, the occasion when form slot part 16f15 in the bottom surface of housing 16f can make that the height (Fig. 9 above-below direction length) of housing 16f is lower, therefore, can make the densification of feeding lubricating device 16.
Again; Shown in Fig. 9 (B); Among the two sides of pivoting part 16g (face parallel with the paper of Fig. 4 is provided with the face of fulcrum 16g1), also can only form side wall surface 16f15a as guide part at the side corresponding with the gyratory directions upstream side of lubricant donor rollers 16a.That is, shown in Fig. 9 (B), the side, right side of the side's of slot part 16f15 side wall surface 16f15a formation and pivoting part 16g is near subtend.Even in this occasion; As above-mentioned for Fig. 7 illustrated; The direction that pivoting part 16g face falls roughly can be confirmed as the corresponding side of gyratory directions upstream side with lubricant donor rollers 16a; Therefore, identical with this example, the effect that the face of the pivoting part 16g that can fully be inhibited falls.
As stated; According to this example, housing 16f takes in the holding member 16c that a pair of pivoting part 16g is set pivotally, is used for making solid shape lubricant 16b to be crimped on lubricant donor rollers 16a; At this housing 16f, be provided with the convex shaped part 16f10 (guide part) that restriction pivoting part 16g face falls.Thus, even along with effluxion can not supplied with the lubricant starvation of photoconductor drum 11 (putting body as carrying), often stable uniform ground supply of lubricant on photoconductor drum 11 yet.
In this example, make each of imaging portion (photoconductor drum 11, charging part 12; Development section 13, cleaning portion 15, feeding lubricating device 16) integrated; Constitute cartridge processing 10Y, 10M, 10C, 10BK, be embodied as the miniaturization of picture portion, improve maintenance operation property.
In contrast, can each one of imaging portion (photoconductor drum 11, charging part 12, development section 13, cleaning portion 15, feeding lubricating device 16) be made as the cartridge processing component parts yet, constitute respectively to change and be arranged on freely in the device body 1 with monomer.This occasion also can obtain the effect identical with this example.
Again; In this example; The present invention is applicable to the image processing system of the development section 13 of bi-component visualization way that carry to use two-component developing agent, certainly, also can be suitable for the present invention for the image processing system of the development section 13 that carries the single component development mode of using monocomponent toner.
In this example, the present invention is applicable to the coloured image of the tandem type that uses intermediate transfer belt 17 forms device again.But; Even the coloured image for the tandem type that uses the transfer printing moving belt forms device (with transfer printing moving belt subtend; Be set up in parallel a plurality of photoconductor drums; With the toner on the photoconductor drum as the device of superimposed transfer printing on the recording medium that transports by the transfer printing moving belt), monochrome image forms device, other image processing systems etc. also can be suitable for the present invention.And, even this occasion also can obtain the effect identical with this example.
Again; In this example; The present invention is applicable to the feeding lubricating device 16 that carries photoconductor drum 11 supply of lubricant of putting body as picture, still, certainly; Carry the feeding lubricating device of putting the body supply of lubricant feeding lubricating device of intermediate transfer belt 17 supply of lubricant (for example to) for the picture beyond the photoconductor drum 11, also can be suitable for the present invention.And even this occasion is identical with this example, the guide part 16f10 that falls through the face that will limit pivoting part 16g is arranged on housing 16f, also can obtain the effect identical with this example.
Again, in this example, use brush shape roller that side face is provided with bristle, still, also can use spongy roller that side face for example is provided with spongy parts (resilient material) as lubricant donor rollers 16a as lubricant donor rollers 16a.And even this occasion is identical with this example, the guide part 16f10 that falls through the face that will limit pivoting part 16g is arranged on housing 16f, also can obtain the effect identical with this example.
Again, in this example, constitute housing 16f, take in solid shape lubricant 16b and holding member 16c, still, also can constitute housing and make it also take in miscellaneous part.For example, also can constitute housing, as the framework housing (shell) of feeding lubricating device 16 integral body.And even this occasion is identical with this example, the guide part 16f10 that falls through the face that will limit pivoting part 16g is arranged on housing 16f, also can obtain the effect identical with this example.
Above with reference to description of drawings example of the present invention, but the present invention is not limited to above-mentioned example.In technological thought scope of the present invention, can do all changes, they all belong to protection scope of the present invention.
