<P>PROBLEM TO BE SOLVED: To provide an image formation device that solves a transfer failure caused by a discharge product at low cost. <P>SOLUTION: An image formation device has toner images superposed on an intermediate transfer belt 113 to be transferred to a record sheet. The intermediate transfer belt 113 is made of a single material and is stretched between a primary transfer roller 126, a secondary transfer counter roller 200 and a driven roller 205. The primary transfer roller 126 and the driven roller 205 are made of metal only, and the outer peripheral surface of the secondary transfer counter roller 200 is covered with a rubber material. In the rubber material covering the secondary transfer counter roller 200, with respect to the resistance value ρs[Ω/sq.] of the intermediate transfer belt 113, the surface roughness Rz [μm] in the circumferential direction falls within the following range. <P>COPYRIGHT: (C)2013,JPO&INPIT |
