<P>PROBLEM TO BE SOLVED: To provide an imaging unit securing quality of an image by stabilizing load torque and electric resistance of an intermediate transfer belt. <P>SOLUTION: A photoreceptor frame 14 and an intermediate transfer frame 18 are integrally constituted, and a primary transfer roller 7 abutting on the inside of the intermediate transfer belt 8 and opposed to a photoreceptor 5 is provided in the photoreceptor frame 14. The primary transfer roller 7 is arranged downstream from a contact of the photoreceptor 5 and the intermediate transfer belt 8 in an advancing direction of the intermediate transfer belt 8, the contact being disposed upstream from the photoreceptor 5 in the advancing direction of the intermediate transfer belt 8, and the intermediate transfer belt 8 is pressed against the photoreceptor 5 side by the primary transfer roller 7 and partially wound round the photoreceptor 5, so that the primary transfer roller 7 is fixed not to rotate. <P>COPYRIGHT: (C)2010,JPO&INPIT |
