[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an image forming apparatus as a cleaning target in which the cleaning jig of the present invention is used will be described. FIG. 1 shows an example of a laser copying machine as the image forming apparatus. In FIG. 1, a drum-shaped image carrier 12 is provided in the copying machine main body 10. Around the image carrier 12, image forming devices such as a charging device 13, a developing device 14, a transfer / conveyance device 15, a cleaning device 16, and a charge eliminating device 17 are disposed.
A laser writing device 18 is provided on the upper part of these image forming devices. A fixing device 25 is disposed on the left side of the cleaning device 16 in the drawing.
A document reading device 30 is provided in the upper part of the copying machine main body 10. On the copying machine main body, an automatic document feeder 41 is attached so as to be openable and closable so as to cover the contact glass 40 installed on the upper surface thereof. On the other hand, a duplex unit 35 is disposed at the lower part of the copying machine main body 10.
The copying machine main body 10 is placed on a paper feed table 43. In the paper feed table 43, a plurality of paper feed cassettes 44 are provided in multiple stages. Each paper feed cassette 44 is provided with a paper feed roller 45 corresponding thereto. Each of the paper feed rollers 45 conveys the sheet fed from the corresponding paper feed cassette 44 to the conveyance path 46.
[0008]
Next, the copying operation of the laser copying machine will be described. In FIG. 1, a copy document is set on the automatic document feeder 41 or on the contact glass 40. When a start switch (not shown) is pressed after setting, the image information of the set document is read by the document reading device 30 in units of pixels.
In response to the document reading operation, a sheet in the paper feeding cassette 44 selected in advance is conveyed to the conveying path 46 by the rotation of the corresponding paper feeding roller 45. The sheet conveyed to the conveyance path 46 is abutted against the registration roller 48 via the sheet feeding path 36 and temporarily stopped. The temporarily stopped sheet is fed below the image carrier 12 as the registration roller 48 rotates at a predetermined timing in accordance with the rotation of the image carrier 12.
[0009]
In response to the document reading operation, the image carrier 12 rotates in a predetermined direction. As the image carrier 12 rotates, the surface of the image carrier 12 is first uniformly charged by the charging device 13. Next, the laser writing device 18 irradiates the surface of the image carrier 12 with laser light L corresponding to the image information of the document read by the document reading device 30. As a result, an electrostatic latent image corresponding to the original image is formed on the surface of the image carrier 12. This electrostatic latent image is converted into a visible image (toner image) by the toner in the developer supplied from the developing device 14.
The toner image formed on the image carrier is transferred by the transfer / conveyance device 15 onto a sheet fed below the image carrier 12 by the rotation of the registration roller 48. In this toner image transfer process, toner remaining on the surface of the image carrier 13 without being transferred onto the sheet is removed from the surface of the image carrier 13 by the cleaning device 16. Further, the charge remaining on the surface of the image carrier 13 after the transfer process is neutralized by the neutralization device 17.
[0010]
The sheet on which the toner image has been transferred in the transfer step is conveyed to the fixing device 25 by the transfer / conveyance device 15. The fixing device 25 fixes the toner image transferred in the transfer process on the sheet. The sheet on which the toner image is fixed is discharged onto a tray (not shown) outside the apparatus through a paper discharge path 38. Here, when a toner image is also formed on the back surface of the sheet on which the toner image is fixed, the sheet after the toner image is formed on one side is sent to the duplex unit 35 through the reverse path 39. The sheet sent to the duplex unit 35 is turned upside down, sent to the registration roller 48, and temporarily stopped. In the same way as when copying on one side, the toner image is transferred and fixed on the back side of the sheet, and the sheet is then discharged onto a tray outside the apparatus through a paper discharge path 38.
[0011]
Next, the developing device 14 will be described. FIG. 2 shows an example of the configuration of the developing device 14. In FIG. 2, the developing device 14 includes a developing tank 50 and a developing hopper 60. In the developing case 59 of the developing tank 50, a first developing roller 51 and a second developing roller 52 are provided as developer carriers. Further, a paddle wheel 53, a stirring roller 54, a conveying screw 55, a separator 56, and the like are provided. Further, the developing device 14 is provided with a doctor blade 57 made of a plate-like member as a developer regulating member so as to face the peripheral surface of the first developing roller 51. In the developing case 59, a two-component developer composed of a carrier and a toner is accommodated. On the other hand, in the developing hopper 60, a toner supply member 61, a supply regulating plate 62, an agitator 63, and the like are provided. In the developing hopper 60, replenishment toner is accommodated.
[0012]
In FIG. 2, the developer in the developing case 59 is stirred and frictionally charged by the rotation of the stirring roller 54, and then carried on the surfaces of the first developing roller 51 and the second developing roller 52 by the rotation of the paddle wheel 53. Is done. The developer carried on the surfaces of the first developing roller 51 and the second developing roller 52 passes through a gap (doctor gap) formed between the first developing roller 51 and the second developing roller 52, thereby thinning the developer to a predetermined thickness. It becomes. The doctor gap of the developing device 14 is set to about 0.6 mm. The electrostatic latent image formed on the surface of the image carrier 12 is converted into a toner image by the toner in the developer supplied from the developing device 14 by the toner in the thinned developer. The
[0013]
The developing device 14 is provided with a toner scattering prevention device 70 (see FIG. 1). The toner scattering prevention device 70 includes an exhaust unit 72 connected to the developing device 14 by an intake tube 71. The exhaust means 72 sucks the scattered toner. The scattered toner sucked by the exhaust unit 72 is stored in the toner storage unit 74 disposed in the copying machine main body 10 through the exhaust tube 73.
[0014]
A suction duct 75 is attached to the tip of the exhaust tube 71 as shown in FIG. The suction duct 75 is formed in an elongated rectangular shape, and a connection port 76 for connecting one end of the intake tube 71 is provided at the center of the upper surface. Further, an opening 77 is provided on the lower surface of the suction duct 75 as shown in FIG.
[0015]
By the way, in the developing device 14 configured as described above, paper dust may be clogged in the doctor gap between the first developing roller 51 and the doctor blade 57. At the portion where the paper gap in the doctor gap is clogged, the thickness of the developer thin layer formed on the first developing roller 51 is changed from the normal state shown in FIG. 5A to FIG. 5B. As shown, it may decrease. As described above, when the thickness of the developer thin layer is reduced, the developing ability is lowered, and the image density of the toner image may be partially reduced.
This problem can be solved by using a cleaning jig according to each embodiment described below.
[0016]
(Embodiment 1)
The cleaning jig according to Embodiment 1 has the following characteristics. FIG. 6 shows an example of the cleaning jig 100 according to the first embodiment. The cleaning jig 100 includes a gripping part 100A, a free end part 100B, and a contact part 100C. Further, the free end 100B of the cleaning jig body is formed of a film-like elastic body. The cleaning jig main body may be made of any material as long as at least the free end 100B is a film-like elastic body. For example, a resin film can be used. Moreover, the thickness of the cleaning jig main body is formed thinner than the size of the doctor gap. Here, this cleaning jig main body was made of PET (polyethylene terephthalate) having a thickness of 0.1 mm. As shown in FIG. 6, the contact portion 100 </ b> C is formed by bending the tip of the cleaning jig main body into an L shape.
This cleaning jig 100 is used as follows by an operator. First, the operator holds the holding portion 100A of the cleaning jig main body. Then, the grasped free end 100B of the cleaning jig main body is caused to enter the doctor gap G between the first developing roller 51 and the doctor blade 57 as shown in FIG. Thereby, the contact portion 100 </ b> C of the cleaning jig main body contacts the inner surface of the distal end portion of the doctor blade 57. Thus, the operator moves the cleaning tool main body along the doctor gap G in a state where the contact portion 100C is in contact with the inner surface of the distal end portion of the doctor blade 57. As a result, adhering substances such as paper dust and toner lump that adhere to the inner surface of the distal end of the doctor blade 57 are removed.
[0017]
(Embodiment 2)
By the way, the cleaning jig 100 according to the first embodiment is applied with a force in a direction in which the bending of the contact portion 100C is eliminated. When such a force is applied, the bending angle of the contact portion 100 </ b> C increases, and the contact portion 100 </ b> C does not contact the inner surface of the distal end portion of the doctor blade 57. For this reason, it has become clear that it is difficult for the cleaning jig 100 to reliably clean the inner surface of the distal end of the doctor blade 57. Here, although the cleaning jig main body is made of a thin metal plate, the bending of the contact portion 100C can be made difficult to return, but the insertion of the contact portion 100C into the doctor gap G becomes very difficult.
The cleaning jig according to the second embodiment solves the problem of the cleaning jig 100 according to the first embodiment. FIG. 8A shows a plan view of the cleaning jig 200 according to the second embodiment, and FIG. 8B shows a side view. The cleaning jig 200 includes a gripping part 200A, a free end part 200B, and a contact part 200C. The free end 200B of the cleaning jig main body is made of PET (polyethylene terephthalate) having a thickness of 0.1 mm, like the cleaning jig 100 according to the first embodiment. As shown in FIG. 8A, the cleaning jig 200 has a contact portion 200C formed by forming a U-shaped cut 200D at the tip of the cleaning jig main body.
Here, the portion that becomes the free end of the abutting portion 200C is directed to face the inner surface of the distal end portion of the doctor blade 57 in a state where the free end portion 200B of the cleaning jig main body has entered the doctor gap G. Is formed.
Moreover, the edge part of the said cut | interruption 200D used as the root part of 200 C of contact parts of the cleaning jig 200 is formed in R shape.
Further, the portion that becomes the side edge of the contact portion 200C is inclined so that the portion that becomes the free end of the contact portion 200C of the cleaning jig 200 forms the short side of the pair of parallel opposing sides of the trapezoid. Is formed.
[0018]
The cleaning jig 200 is used by an operator as follows. As shown in FIG. 9, the operator grasps the grasping portion 200 </ b> A of the cleaning jig main body, and causes the free end portion 200 </ b> B to enter the doctor gap G between the first developing roller 51 and the doctor blade 57. When the free end 200B of the cleaning jig 200 is further advanced into the doctor gap G in this way, the tip of the free end 200B is brought into contact with the wall 14A provided in the developing device 14, as shown in FIG. Abut. Thereby, the advance of the tip of the free end portion 200B is blocked by the wall portion 14A, and the free end portion 100B is curved. Then, the free end of the contact portion 200 </ b> C of the cleaning jig 200 is bent and raised at a portion facing the inner surface of the distal end portion of the doctor blade 57. In this way, with the free end of the abutting portion 200 </ b> C bent and raised at a position facing the inner surface of the distal end portion of the doctor blade 57, the cleaning jig 200 is pulled lightly in the direction of pulling out from the doctor gap G.
Thereby, the contact portion 200C of the cleaning jig main body comes into contact with the inner surface of the distal end portion of the doctor blade 57 as shown in FIG. In this manner, the operator moves the cleaning tool main body along the doctor gap G while the contact portion 200 </ b> C remains in contact with the inner surface of the distal end portion of the doctor blade 57. As a result, adhering substances such as paper dust and toner lump that adhere to the inner surface of the distal end of the doctor blade 57 are removed. In the developing device 14 shown in FIG. 2, a part of a member that forms the Q shadow portion of the scattered toner by the toner scattering preventing device 70 serves as the wall portion 14A.
[0019]
