<p><P>PROBLEM TO BE SOLVED: To provide an image forming apparatus in which primary transfers from a plurality of photoconductors to an intermediate transfer belt are respectively conducted appropriately. <P>SOLUTION: In the image forming apparatus comprising the intermediate transfer belt in a form of endless loop stretched over a plurality of stretch rollers to move around, the plurality of photo conductors aligned along the intermediate transfer belt, a plurality of primary transfer rollers which respectively opposes to the photoconductors and is pressed against the photoconductor with interposition of the intermediate transfer belt to form a nip, and a power source for applying a voltage to the primary transfer rollers, the primary transfer rollers being arranged to be shifted with reference to the photoconductors in the moving direction of the intermediate transfer belt, a shifted amount D of the primary transfer roller 6Y adjacent to the stretch roller with reference to the photoconductor 9 is different from that of another primary transfer roller with reference to the respective photoconductors. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
