摘要： PROBLEM TO BE SOLVED: To dispense with the erasing of the polarity of a photoreceiving body in the case of re-electrification in an electrophotographic color printer having a system of the re-electrification of an image on an image, exposure and development (REaD 101). SOLUTION: This color printer is provided with a first electrifying device 20 by which the potential of the photoreceiving body is reduced by jetting an ion having a polarity for reducing a charge on an image area first when the photoreceiving body 10 is electrified between the developing of the toner image of one color and the exposure of the latent image of a succeeding color, and a second electrifying device 22 electrifying the photoreceiving body 10 with the ion having a reverse polarity and re-electrifying it to a required level.

摘要： PROBLEM TO BE SOLVED: To realize REaD electrophotographic printing using additive color process toner by restraining image-on-image development. SOLUTION: An image area passes through an electrification station constituted of a DC scorotron 22 electrifying the image area. After the image area passes through a black developing station 32, a DC scorotron 42 electrifies the image area and a black toner layer again. In a blue exposure station 44, the image area is exposed to obtain the electrostatic latent image of a blue image. The image area passes through a blue developing station 46, and blue toner 48 is stuck to the image. A DC scorotron 52 electrifies the image area again. Next, the image area is exposed by a green exposure station 54, and green toner 58 is adhered to the image area. Then, the image area is electrified by a DC scorotron 62 again. The image area exposed again after passing through a red exposure station 66 passes through a red developing station 66, and red toner 68 is adhered to the image area.

摘要： PROBLEM TO BE SOLVED: To update the software code of a machine, e.g. a printer, using a client replaceable unit (CRU) without requiring to call a service engineer.
SOLUTION: The replaceable subassembly (CRU) 1 separable from the machine 100 has a memory (CRUM) 30. The memory stores the software code/upgrade of an executable instruction concerning to utilization of the replaceable subassembly. In the operation of the machine, the replaceable subassembly is placed in the machine and the memory is read out. The stored software code/upgrade is then placed in the machine as a new executable instruction, and a machine having the replaceable subassembly is operated based on the new executable instruction.

摘要： PROBLEM TO BE SOLVED: To arrange all of respective devices and respective stations proximately to a photoreceptor and to realize a small-sized desk top color printer by arranging an erasing lamp on the opposide side or on this side of a final physical developer housing but behind from a first physical developer housing. SOLUTION: A pretransfer erasing lamp 39 is arranged on the upstream side of a magenta developing station 32 and on the downstream side of a cyan developing station 34. Furthermore, the lamp 39 is arranged proximately to the inside surface of a photoreceptor belt 10. By arranging the lamp 39 at this position, compact design is realized especially. In the case of requiring to maintain the stability and the consistency of the charge of the photoreceptor, the delay of time between the discharge of the lamp 39 and an electrifier 40 should be made to a minimum. Therefore, it is still beneficial to put the lamp 39 on this side of a final developer housing even when there exists an appropriate space where the lamp 39 can be arranged behind the final developer housing.

摘要： PROBLEM TO BE SOLVED: To solve problems such as update of a software code of a machine using a replaceable unit, without requiring any call for a field engineer and the like. SOLUTION: A replaceable assembly 1 separable from the machine 100 such as a printer and having a memory is prepared, while the memory 30 (CRUM) stores the software code of an operable instruction related to the operation of the machine inside itself. Then, the replaceable subassembly is placed inside the machine, the memory is read, and the software code of the stored operable instruction is placed inside the machine as a new software code. In the final step, the machine is operated according to the software code. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide an electrophotographic device including a braid sticker making it possible to provide a functional housing, enabling the electrophotographic device to operate while preventing suspended toner particles from leaking out to a wrong area in the device, at the circumference of a photodetection body.
SOLUTION: In an electrophotographic printer, the surface of the photodetection body 10 which rotates is cleaned by using a blade 22. At an end part of the blade 22, a flexible seal member 70 is provided. The seal member 70 has a main body part 76 and a portion of it comes into contact with the surface of the photodetection body 10 while the other part is fixed to a stationary surface. A tab forming an oblique edge 72 is extended from the main body part 76. A portion of the oblique edge 72 comes into contact with the surface of the blade 22.

摘要： PROBLEM TO BE SOLVED: To prevent the print quality of a form sending-in guide in a transfer area from deteriorating. SOLUTION: A printer is equipped with an electric charge receptor such as a photoreceptor 10, a transfer corotron 14 which determines the transfer area associated with the electric charge receptor, and a peeling corotron 16 and further a guide member 18 which sends a sheet in the transfer area is provided in the transfer area. The guide member 18 has a plurality of ribs (30) supports the sheet in the transfer area so that it moves in a processing direction (in the moving path direction of the sheet). A 1st group of ribs (30) is set to a direction oblique to the processing direction and a 2nd group of ribs is set to a 2nd direction oblique to the processing direction. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To minimize a total charge imparted to a toner layer and to reduce a mutual pollorion by making a lamp irradiate a photoreceptor and removing the charge of the photoreceptor before the next AC re-electrification of the photoreceptor, which is performed to expose a next color image, after developing the 1st toner layer. SOLUTION: Re-electrification is performed well when a photoreceptor is exposed first so that the charge of an image area is made to lower before the re-electrification. Then, a pre-electrification erasing lamp 18 is used to expose the image area. When the image area advances passing through the lamp 18, the lamp 18 irradiates the image area. The developed image area is discharged by the lamp 18 and the potential of the photoreceiving body is lowered to the potential obtained by adding all voltages to a residual voltage being about -25 V by a charge on a developed toner. After passing through the lamp 18, an AC scorotron 22 re-electrifies the image area to a charge level which is desirable to expose and develop a yellow image.
