摘要： In an intermediate transfer part (100), a bead 107 is formed on an inner side of an intermediate transfer belt (102), which is rotated by an intermediate transfer belt drive roller (101). Driven roller bearings (104a, 104b) support an intermediate transfer belt driven roller (103). The intermediate transfer belt driven roller (103) is movable in a thrust direction. Ends of the intermediate transfer belt driven roller (101) and the intermediate transfer belt driven roller (103) interfere with a bead (107) so as to restrict a deflection of the intermediate transfer belt in the thrust direction. The intermediate transfer belt driven roller (103) is movable in the thrust direction against a deflection of the intermediate transfer belt (102).

摘要： A belt driving device (30) is provided and includes a plurality of rollers (32, 33, 34, 35) including a driving roller (34). A belt (31) is configured to be tensioned by the plurality of rollers (32, 33, 34, 35), and to be driven by the driving roller (34). The driving roller (34) is arranged adjacent to where an outside body (510) contacts an outer surface of the belt (31). A pair of fluctuation absorbing members (800, 900) may be configured to absorb tensional fluctuation of the belt (410) at an upstream and a downstream of a cleaning member (151) in a direction which the belt (410) is driven. A detecting means (680) may be utilized to detect a driving load of one of the driving roller (34) and the outside roller (510) and a controller (620) is configured to drive another roller of the driving roller (34) and the outside roller (510) based on the driving load detected by the detecting means (680). An outside roller (510) may be configured to contact an outer surface of the belt (31) and to be driven by a second motor (M2); a controller (620) configured to control the second motor (M2) by a less loop gain than a loop gain to control the first motor (M1).

摘要： An image forming apparatus includes an image bearing member that bears a visual image, a visual image forming device that forms the visual image on the image bearing member, and a two-side transfer device including a recording medium holding member spanning a plurality of stretch members to hold a recording medium thereon. The two-side transfer device transfers the visual images on the image bearing member onto both sides of the recording medium on the recording medium holding member while the recording medium holding member is being moved in a predetermined direction. The image bearing member intrudes into a part of the recording medium holding member spanning two adjacent ones of the plurality of stretch members by an intrusion amount of about 0.2 mm or greater so that the recording medium holding member moves in contact with the image bearing member, having a contact width in a predetermined direction.

摘要： An electrophotographic printer. The electrophotographic printer includes: a backup roller (113) for supporting a photosensitive belt (111); a pressing roller (102) for pressing a supplied paper (101); a transfer roller (103) selectively contacting or separated from the backup roller (113) and the pressing roller (102) while moving forward or backward between the backup roller (113) and the pressing roller (102); and a driving unit for moving the transfer roller (103) forward and backward. Therefore, the transfer roller (103), the backup roller (113) and the pressing roller (102) are easily aligned with accuracy, and the impacts occurring when the rollers contact each other and are separated from each other are alleviated.

摘要： In forming a first image and a second image on both sides of a recording paper by using an electrophotographic process, the first image is generated on a photosensitive drum (3a), and is transferred to an intermediate transfer belt (5) which can transfer and hold a developer image. The photosensitive drum (3a) and the intermediate transfer belt (5) is disposed across a plane where the recording paper is conveyed. Subsequently, the second image is generated on the photosensitive drum (3a) after a developer remaining thereon has been removed, and is transferred to one side of the recording paper. After the second image has been fixed on one side of the recording paper, the first image is transferred from the intermediate transfer belt (5) to the other side of the recording paper and fixed.

摘要： An image forming apparatus includes an image member (2) supplied to the apparatus in an image member cartridge (3) and a transfer member (10) which engages the image member through an access opening in the cartridge. The transfer member (10) is driven by a motor (40; 212), which may be inside the transfer drum, in the image forming apparatus and in turn drives the image member (2) in the cartridge, eliminating the need for a separate driving connection between the image forming apparatus and the image member cartridge. The cartridge is mounted in the image forming apparatus by a pair of control surfaces (115) which are fixed with respect to the shaft (111) of the transfer drum along which extensions of the shaft (105) of the image member are urged by a spring (120).

摘要： An image transferring device (1) incorporated in an image forming apparatus and capable of surely preventing a sheet from wrapping around a photoconductive element (2) and from being incompletely separated from a transfer belt (5). A transfer bias and discharge are effected to prevent changes in the resistances of the transfer belt (5) and sheet ascribable to changes in environment from translating into changes in a current to flow to the photoconductive element (2), and to efficiently dissipate a charge deposited on the belt (5). Various members constituting the device are positioned relative to one another such that the discharging effect is achievable most effectively while preventing the transfer bias from causing dielectric breakdown in any constituent part.
