BEST MODE FOR CARRYING OUT THE INVENTION A mode for carrying out the present invention will be exemplarily described in detail below based on an embodiment with reference to the drawings. It should be noted that the dimensions, materials, shapes, and relative arrangement of the components described in this embodiment should be appropriately changed according to the configuration of the device to which the invention is applied and various conditions. Also, not all combinations of features described in the present embodiment are essential for the solution means of the present invention. Components described in the embodiments are merely examples, and are not intended to limit the scope of the present invention only to them.

(Example 1)
<Overall Configuration of Image Forming Apparatus>
An electrophotographic image forming apparatus (image forming apparatus) is an apparatus that forms an image on a recording sheet such as a sheet (also referred to as recording material, recording medium, etc.) using an electrophotographic image forming method. Examples of image forming apparatuses include electrophotographic copiers, electrophotographic multifunction machines, electrophotographic printers (LED printers, laser beam printers, etc.), facsimile machines, word processors, and the like. In the embodiments of the present invention, a laser beam printer will be described as an example.

The electrophotographic image forming method refers to a method in which an electrostatic image formed on an electrophotographic photoreceptor (photoreceptor) is developed with toner (developer). Here, the developing method is not related to a developing method such as a one-component developing method, a two-component developing method, or a dry developing method. As the photoreceptor, an electrophotographic photosensitive drum (photosensitive drum) having a configuration in which a drum-shaped cylinder surface layer is provided with a photoreceptor is used. A charging roller, a developing roller, and the like that act on the photosensitive drum in image formation are called process means.

Here, the photoreceptor and the process means may be individually or integrally made into a cartridge, and configured to be detachable (detachable) from the apparatus main body of the image forming apparatus. For example, a developing device including developing means such as a developing roller may be configured as a developing cartridge that can be attached to and detached from the main body of the image forming apparatus. In this embodiment, a process cartridge in which a photosensitive drum as a photoreceptor and a charging roller, a developing roller and a cleaning blade as process means are integrated will be described as an example.

It should be noted that the reference numerals in the examples are for referring to the drawings and do not limit the configuration. Also, the dimensions and the like in the examples are for the purpose of clearly explaining the relationship, and are not intended to limit the configuration.

Further, the longitudinal direction of the process cartridge in the embodiments is a direction substantially orthogonal to the direction in which the process cartridge is attached to and detached from the main body of the image forming apparatus. Further, the longitudinal direction of the process cartridge is parallel to the rotational axis of the photosensitive drum (the direction intersecting with the sheet conveying direction). In the longitudinal direction, the side of the process cartridge on which the photosensitive drum receives rotational force from the image forming apparatus main body is called the driving side (driven side), and the opposite side is called the non-driving side. In addition, when the term "upper" is used without specifying otherwise, the upper side in the direction of gravity when the image forming apparatus is installed is regarded as the upper side, and the opposite direction (reverse direction) is the lower side in the direction of gravity (lower side). ).

<Explanation of Laser Beam Printer and Image Forming Process>
FIG. 5 is a schematic cross-sectional view of an apparatus main body A (hereinafter referred to as apparatus main body A) and a process cartridge (hereinafter referred to as cartridge B) of a laser beam printer, which is an image forming apparatus according to this embodiment. . 6 is a schematic cross-sectional view of the cartridge B. FIG.

Here, the device main body A refers to the configuration of the laser beam printer, excluding the cartridge B. As shown in FIG.

The configuration of the laser beam printer will be described with reference to FIG. In the laser beam printer shown in FIG. 5, the cartridge B is detachable (mountable and detachable) with respect to the apparatus main body A. When the cartridge B is mounted on the apparatus main body A, the exposure means (exposure device) ) below the laser scanner unit 3 . Further, below the cartridge B mounted in the apparatus main body A, a sheet tray 4 containing sheets P as a recording medium (sheet material) which is an object (purpose) of image formation in the image forming apparatus is arranged. .

Further, in the apparatus main body A, a pickup roller 5a, a pair of feeding rollers 5b, a pair of conveying rollers 5c, a transfer guide 6, a transfer roller 7, a conveying guide 8, and a fixing roller are arranged in this order from the upstream side along the conveying direction X1 of the sheet P. A device 9, a pair of discharge rollers 10, and a discharge tray 11 are arranged. The fixing device 9 as fixing means is composed of a heating roller 9a and a pressure roller 9b.

An outline of the image forming process will be described with reference to FIGS. 5 and 6. FIG.

Based on the print start signal, a drum cylinder 62 as a photosensitive drum is rotationally driven in the direction of arrow R (hereinafter referred to as rotation direction R) at a predetermined peripheral speed (process speed). A charging roller 66 to which a bias voltage is applied contacts the outer peripheral surface of the drum cylinder 62 and uniformly charges the outer peripheral surface of the drum cylinder 62 .

The laser scanner unit 3 outputs laser light L according to image information input to the laser beam printer. The laser light L passes through the exposure window 74 on the upper surface of the cartridge B, and scans and exposes the outer peripheral surface of the drum cylinder 62 . As a result, a portion of the charged drum cylinder 62 is discharged, and an electrostatic image (electrostatic latent image) is formed on the surface of the photosensitive drum.

On the other hand, as shown in FIG. 6, in the developing unit 20 as a developing device, the developer (hereinafter referred to as "toner T") in the toner chamber 29 is agitated and transported by the rotation of the transport screw 43 as a transport member. and sent to the toner supply chamber 28 .

Toner T as a developer is carried on the surface of a developing roller 32 as developing means by the magnetic force of a magnet roller 34 (fixed magnet). The developing roller 32 has a drum cylinder 62
A developer material is carried and transported to the development zone to develop the electrostatic latent image formed thereon. The layer thickness of the toner T conveyed to the development area is regulated by the development blade 42 on the peripheral surface of the development roller 32 . The toner T is triboelectrically charged between the developing roller 32 and the developing blade 42 .

The toner T carried by the developing roller 32 in this manner develops (visualizes) the electrostatic latent image formed on the drum cylinder 62 . Then, the drum cylinder 62 rotates in the rotational direction R while bearing the developed toner (toner image) on its surface.

Also, as shown in FIG. 5, the sheet P stored in the lower part of the apparatus main body A is moved by the pickup roller 5a, the feeding roller pair 5b, and the conveying roller pair 5c in accordance with the output timing of the laser beam L to the sheet tray. 4 is fed. Then, the sheet P is fed to a transfer position (transfer nip) between the drum cylinder 62 and the transfer roller 7 via the transfer guide 6 . At this transfer position, the toner image is sequentially transferred from the drum cylinder 62 onto the sheet P. As shown in FIG.

The sheet P to which the toner image has been transferred is separated from the drum cylinder 62 and conveyed along the conveying guide 8 to the fixing device 9 . Then, the sheet P passes through a fixing nip portion between a heating roller 9 a and a pressure roller 9 b that constitute the fixing device 9 . At this fixing nip portion, the unfixed toner image on the sheet P is fixed to the sheet P by applying pressure and heating. After that, the sheet P on which the toner image is fixed is conveyed by the discharge roller pair 10 and discharged to the discharge tray 11 .

On the other hand, on the surface of the drum cylinder 62 after the toner T has been transferred onto the sheet, transfer residual toner remains on the drum surface without being transferred onto the sheet. This transfer residual toner is removed by a cleaning blade 77 that abuts on the peripheral surface of the drum cylinder 62 . As a result, toner remaining on the drum cylinder 62 is cleaned, and the cleaned drum cylinder 62 is charged again and used in the image forming process. The toner removed from the drum cylinder 62 (transfer residual toner) is stored in the waste toner chamber 71 b of the cleaning unit 60 .

In the above, the charging roller 66 , the developing roller 32 and the cleaning blade 77 all function as process means acting on the drum cylinder 62 . The image forming apparatus of the present embodiment employs a method of removing the transfer residual toner by the cleaning blade 77, but adopts a method (cleanerless method) of recovering the transfer residual toner whose charge is adjusted by the developing device at the same time as the development. may In the cleanerless method, an auxiliary charging member (auxiliary charging brush or the like) for adjusting the charge of the residual toner also functions as a process means.

In addition, the pair of groove-shaped portions have regulating surfaces which are surfaces facing in the D2 direction, sandwich the substrate 81 (the end surface of the edge in the width direction) in the width direction, and determine the position of the substrate 81 in the D2 direction. .

As shown in FIG. 4, the information storage member 80 is arranged in the slit portion 90c from the direction of the dashed arrow in the drawing to the side of the substrate 81 on which the memory element contacts 82 are provided (the other side shown in FIG. 9B). ) facing outward (toward D3 direction). In the information storage member 80, the substrate 81 is fitted into the slit portion 90c, and the position of the information storage member 80 in the cartridge lateral direction (width direction (D2 direction) perpendicular to the insertion direction of the substrate 81) is determined. With respect to the longitudinal direction of the information storage member 80 (the insertion direction (D1 direction) of the substrate 81), the tip portion of the information storage member 80 (the downstream end surface portion of the substrate 81 in the insertion direction) is provided deep in the slit portion 90c. The position is determined by abutting against the regulation wall (contact portion) 90d (FIG. 14). That is, at this time, the information storage member 80 is restricted from moving in directions other than along the groove shape of the slit portion 90c by the shape of the restriction wall 90d in the second mounting portion 90g and the ribs of the surrounding slit portion 90c. ing.

As described above, a part of the shape is left in the step of cutting and removing the periphery of the first mounting portion 71 e of the cleaning frame 71 , and the remaining portion can be used for positioning the information storage member holding unit 90 .

According to this configuration, a new information storage member 80 having the same size as the information storage member 80 of the material cartridge (pre-reproduction cartridge B1) can be placed in the second attachment portion 90g of the post-reproduction cartridge B2. Therefore, it is possible to provide a remanufacturing method in which the new information storage member 80 is attached to the remanufactured cartridge B2 in a simpler process than the conventional method and positioned accurately. In addition, since the mounting portion (first mounting portion 71e) of the material cartridge (cartridge B1 before remanufacturing) may be integrally molded with the cartridge frame (cleaning frame 71), the cost of the material cartridge is not increased. high-accuracy positioning is possible.

<Information Storage Member of Remanufactured Cartridge>
A method of holding the information storage member 80 of the remanufactured cartridge B2 will be described with reference to FIGS. FIG. 11 is a schematic diagram illustrating the relationship between the information storage member holding unit 90 and the main body connector 84 in this embodiment. FIG. 11(a) is a perspective view illustrating a state before the body connector 84 is engaged with the information storage member holding unit 90. FIG. 11B is a top view showing the relationship between the cleaning frame 71 and the information storage member holding unit 90. FIG. 11(c) is a partial cross-sectional view (cross-sectional view taken along arrows XX in FIG. 11(b)) showing a state in which the main body connector 84 is engaged with the information storage member holding unit 90. FIG. FIG. 12 is a schematic perspective view explaining the process of inserting the information storage member 80 into the information storage member holding unit 90. FIG. FIG. 13 is a schematic perspective view explaining the arrangement of the memory element contacts 82 of the information storage member 80. As shown in FIG. FIG. 14 is a schematic perspective view for explaining the positional accuracy of the information storage member 80 and the information storage member holding unit 90. FIG.

The remanufactured cartridge B2 has the cleaning frame 71 and the information storage member holding unit 90. By engaging the information storage member holding unit 90 with the main body connector 84, the information storage member holding unit 90 and the main body connector 84 are connected. positioning. Specifically, as shown in FIGS. 11(a) to 11(c), the pair of second positioning ribs 90e and 90f provided in the information storage member holding unit 90 are aligned with the pair of protrusions 84e and 84e of the main body connector 84, respectively. Positioning is performed by sandwiching with 84f and fitting them.

The pair of positioning ribs 90e and 90f of the information storage member holding unit 90 protrude in the D3 direction, which is the direction in which the memory element contacts 82 of the information storage member 80 are exposed, and extend in the width direction of the substrate 81 of the information storage member 80. It has a rib shape extending in the D2 direction. The pair of protrusions 84e and 84f of the main body connector 84 are a pair of protrusions that protrude in the D3 direction (the direction opposite to the direction in which the memory element contacts 82 are exposed) and are aligned in the D1 direction. The pair of projecting portions 84e and 84f of the main body connector 84 are configured so that they can be fitted by sandwiching the positioning ribs 90e and 90f in the D1 direction.

Therefore, the positioning accuracy of the main body connector 84 and the information storage member holding unit 90 is high in the direction perpendicular to the d1 direction (the direction in which the positioning ribs 90e and 90f extend) in FIG. 11 (the direction in which the main body connector 84 is fitted).

In the pre-reproduction cartridge B1, the first positioning ribs 71G and 71H of the cleaning frame 71 shown in FIG. The first attachment portion 71e (information storage member 80) is positioned. The remaining ribs 71g and 71h as remaining portions are parts of the first positioning ribs 71G and 71H remaining after the cutting process described above.

The second positioning ribs 90e and 90f of the remanufactured cartridge B2 are provided so as to form continuous ribs connected to the remaining ribs 71g and 71h, respectively. That is, the second positioning ribs 90e and 90f are configured to form the same rib shape as the first positioning ribs 71G and 71H of the pre-reproduction cartridge B1 integrally with the remaining ribs 71g and 71h. . The positioning accuracy of the information storage member 80 with respect to the apparatus main body A is configured so as not to change before and after reproduction.

The positioning ribs 71G and 71H of the pre-remanufacturing cartridge B1 also serve to position the cleaning frame 71 with respect to the apparatus main body A (to-be-fitted portion) and to position the information storage member holding unit 90 with respect to the cleaning frame 71 during remanufacturing. It has a positioning function (engaged portion). These two functions may be achieved by separate shape portions, but in this embodiment, one rib shape portion is configured to serve the above two functions.

Here, the protrusion pair 84e of the main body connector 84 as the fitting portion may be configured to sandwich the second positioning rib 90e and the remaining rib 71h connected thereto as the fitting portion in the D1 direction. . Similarly, the projection pair 84f of the main body connector 84 may be configured to sandwich the second positioning rib 90f and the remaining rib 71g connected thereto in the D1 direction. As a result, it is possible to more effectively suppress variation in the position of the information storage member 80 with respect to the apparatus main body A before and after reproduction.

Further, in the remanufactured cartridge B2, the second positioning ribs 90e and 90f are configured to be closely connected to the remaining ribs 71g and 71h, respectively. That is, the side surfaces of the second positioning ribs 90e and 90f having the same height and width as the remaining ribs 71g and 71h are closely opposed to the cut surfaces of the remaining ribs 71g and 71h formed by the cutting process. The corner portion between the tip of 71h and the cutting surface is not exposed to the apparatus main body A side. In this way, the information storage member holding unit 90 has a shape following the remaining shape portion of the cleaning frame 71, and by minimizing the clearance between the remaining shape portion and the information storage member holding unit 90, the apparatus main body A can be reproduced. It is possible to suppress catching when the postpartum cartridge B is attached or detached.

In addition, in this embodiment, as a configuration to be fitted when positioning with the apparatus main body A, rib shapes such as the first positioning ribs 71G and 71H and the second positioning ribs 90e and 90f are adopted. Such a thin rib shape reduces the influence of sink marks, especially in a resin frame manufactured by injection molding. becomes.

Further, in this embodiment, the configuration in which the first attachment portion 71e is formed integrally with the cleaning frame 71 in the pre-remanufacturing cartridge B1 is adopted. For example, it is conceivable to manufacture the first attachment portion 71e separately from the cleaning frame 71 before remanufacturing, and attach it to the cleaning frame 71 afterward. be able to.

In this embodiment, the mounting mode (slit portion 71c) of the information storage member 80 in the first mounting portion 71e is configured in the same manner as the slit portion 90c in the second mounting portion 90g. Different configurations are possible. For example, the insertion direction of the information storage member 80 into the slit portion 71c may be opposite to the insertion direction into the slit portion 90c.

A method of positioning the information storage member 80 with respect to the information storage member holding unit 90 will be described with reference to FIG. The information storage member 80 is inserted into the slit portion 90c provided in the information storage member holding unit 90 in the direction of the arrow d2 in the drawing, and the information storage member 80 is inserted into the regulation wall 90d provided on the back side of the slit portion 90c. abut. There is play between the width of the slit portion 90c and the information storage member 80 in the width direction (D2 direction) orthogonal to the insertion direction d2 of the substrate 81 of the information storage member 80. FIG. Therefore, the positioning accuracy of the information storage member 80 with respect to the information storage member holding unit 90 is higher in the direction along the d2 direction than in other directions orthogonal to the d2 direction.

As shown in FIG. 13, the memory element contacts 82 of the information storage member 80 are provided so as to line up in a plurality (pairs) in the d3 direction. coincides with the insertion direction d2 of . Furthermore, the area in which each storage element contact 82 can contact the main body electrical contact 85 is different from the d2 direction in which the information storage member 80 has high positioning accuracy, whereas the D2 direction (d2 direction). Specifically, the width a in the D2 direction orthogonal to the alignment direction d3 of the memory element contacts 82 in the contactable region is wider than the width b in the alignment direction d3.

The plurality of memory element contacts 82 are required to be aligned with high positioning accuracy in the direction in which the plurality of body electrical contacts 85 of the body connector 84 are aligned. Since the alignment direction d3 of the plurality of memory element contacts 82 coincides with the d2 direction in which the information storage member 80 has high positioning accuracy, even if the width b of the memory element contacts 82 in the alignment direction d3 is designed to be narrow, the main body electric Reliable contact with the contact 85 can be ensured. Furthermore, the width a of the memory element contacts 82 can be designed to be wide in the D2 direction (the direction perpendicular to the alignment direction d3) in which the looseness between the slit portion 90c and the information storage member 80 is large. Therefore, the information storage member 80 can be positioned with high accuracy with respect to the body electrical contacts 85 .

The old information storage member 80 attached to the pre-reproduction cartridge B1, which is a material cartridge, and the new information storage member 80 attached to the post-reproduction cartridge B2 have the same configuration. That is, the memory element contact 82 as the first electrode of the old information storage member 80 as the first memory member and the memory element contact 82 as the second electrode of the new information storage member 80 as the second memory member. and are constructed similarly.

As described above, the d1 direction in which the positioning ribs 90e and 90f extend is arranged in a direction orthogonal to the d3 direction with respect to the d3 direction in which the required position accuracy is high, and the d2 direction, which is the insertion direction of the information storage member 80, is the same direction as the d3 direction. It is desirable from the standpoint of product functionality to place it in (Fig. 14).

According to the configuration described above, it is possible to provide a user with a highly reliable remanufactured cartridge in which the positioning accuracy of the information storage member is high even in the remanufactured cartridge.

In this embodiment, the rib shape is adopted as the positioning structure of the cartridge B with respect to the apparatus main body A, but a shape other than the rib may be adopted.

In addition, in the present embodiment, the pair of positioning ribs 71G, 71H, 90e, and 90f extend side by side in the same direction (D2 direction), but the ribs are not limited to such a configuration. For example, one of the pair of ribs may be extended in the D2 direction to provide positional accuracy in the insertion direction d2 of the information storage member 80, and the other may be extended in the D1 direction to extend in the width direction (insertion direction d2) of the information storage member 80. It may be configured to provide positional accuracy in the direction orthogonal to ).

Further, the information storage member 80 of the cartridge B2 may be further refreshed after remanufacturing. That is, the post-remanufacturing cartridge B3 may be formed by cutting and removing the peripheral portion of the information storage member holding unit 90 in the post-remanufacturing cartridge B2 and attaching a new information storage member holding unit. In this case, in cutting the peripheral portion of the information storage member holding unit 90 in the remanufactured cartridge B2, part of the remaining ribs 71g and 71h may be cut.
