摘要:
A transfer belt device includes an endless transfer belt that is tightly stretched by a plurality of rollers and forms a transport path where a recording medium or a developer image is transported facing a monochrome image bearing member and a plurality of color image bearing members arranged in parallel along a fixed direction. In the apparatus, a first transfer unit having a first linking member in which a monochrome-image transfer member is supported that transfers a developer image formed on the monochrome image bearing member onto a recording medium or an outer peripheral surface of the belt, and a second transfer unit having a second linking member in which a plurality of color-image transfer members are supported that transfer developer images formed on the respective color image bearing members onto a recording medium or an outer peripheral surface of the belt, are linked via the first and second linking members.
摘要:
A transfer unit includes: an intermediate transfer belt that (i) holds a toner image that has been transferred, at a primary transfer part, from a photoreceptor drum and (ii) rotates to move a surface holding the toner image; and a secondary transfer belt that comes into contact, at a secondary transfer part, with the intermediate transfer belt. The transfer unit (i) transfers the toner image from the intermediate transfer belt to a sheet conveyed to the secondary transfer part and (ii) includes an intermediate transfer belt cleaning unit that removes and collects toner from the toner image holding surface of the intermediate transfer belt. The transfer unit also includes secondary transfer power source for sequentially applying, to the secondary transfer belt, (i) a first voltage for generating an electric field that transfers normally-charged toner from the secondary transfer belt to the intermediate transfer belt and (ii) a second voltage for generating an electric field that transfers oppositely-charged toner from the secondary transfer belt to the intermediate transfer belt. Therefore, the toner from the secondary transfer belt can be suitably transferred to an intermediate transfer belt, and the secondary transfer belt can be desirably cleaned.

In an MFP having various and many functions and part of the functions introduced as optional functions, in order to appropriately introduce an optional function related to a frequently used function, a CPU of the MFP executes a program including the steps of; receiving and storing information of an optional function recommended for a standard function used frequently, from an FSS server computer (S3110); when a function is selected by a logged-in user (YES at S3020), determining whether or not any recommended optional function is stored (S3030); when a recommended optional function is stored (YES at S3030), displaying an image recommending the optional function related to the function selected by the user (S3050); and transmitting, as a job completing process, selected functions to the FSS server computer (S3080).

Semiconductor laser assembly 1 is provided with semiconductor laser device 6 and heat dissipation member 24. Semiconductor laser device 6 includes semiconductor laser element 15, lead-frame 11, lower and upper enclosures 18 and 19 and plate-like spring 21 connected to lead-frame 11. Semiconductor laser element 15 is mounted on lead-frame 11 through sub-mounting member 16. Lower and upper enclosures 18 and 19 have an opening through which laser beams from semiconductor laser element 15 are emitted. Plate-like spring 21 is connected to lead-frame 11 and has wing and holding portions 22 and 23. Holding portion 23 is a C-character in cross section to put lower and upper enclosures 18 and 19 together. Heat dissipation member 24 has inside walls to define perforation 25, so that wing portions 22 of plate-like spring 21 pushes semiconductor laser device 6 against the inside walls of heat dissipation member 24 when the semiconductor laser device 6 is set in perforation 25.

First eccentric cams for abutting an inner circumferential surface of an intermediate image transferring belt, second eccentric cams for rotating as a unit with the first eccentric cams, cam followers for abutting a circumferential surface of the second eccentric cam, and transmitting members for holding image transferring rollers, moving in response to the cam followers are disposed within a loop-shaped moving path formed by an intermediate image transferring belt, which is stretched across a driving roller and a driven roller. The vertical position of the image transferring rollers, which are held by the transmitting members, changes in accordance with the abutting state of the first eccentric cams with respect to an inner circumferential surface of the intermediate image transferring belt.

An image forming apparatus includes a pair of optical sensing devices for monochrome image forming and full-color image forming which are disposed at the rear of the image forming apparatus and a pair of generally L-shaped light shielding members for monochrome image forming and full-color image forming which are mounted swingably on a rear side of an image transfer unit with one end of each light shielding member attached to one of two sliding members. When each of the sliding members moves back and forth, the light shielding member for monochrome image forming or full-color image forming, whichever applicable, swings and the relevant optical sensing device detects the other end of the light shielding member.

Provided is a strobe unit compatible with both a camera that has a synchro switch that does not cause chattering and that can achieve a large number of times of flash photography per unit time and a camera that has a synchro switch whose chattering time is long or short. The strobe unit comprises: a chattering preventing unit that is connected to a flashlight emission initiating unit; a checking unit that checks the type of synchro switch included in an image sensing apparatus, which is connected to the strobe unit via a communication terminal, through transfer of information with the image sensing apparatus; and a control unit that controls the chattering preventing unit according to the result of checking performed by the checking unit.
