PROBLEM TO BE SOLVED: To provide an image formation device capable of suppressing generation of leak current from a sheet metal member to an image carrier when applying transfer bias voltage.SOLUTION: An image formation device 1 comprises a sheet metal member 9 having a folding ridge line L almost parallel to an axial direction of a base substrate 51 of an image carrier 5. A first portion P1 including a center portion of the folding ridge line L presses the inner peripheral surface of an intermediate transfer belt 3, second portions P2 on both sides of the center portion in the folding ridge line L press a casing 53 of the image carrier 5, and a third portion P3 positioned between the first portion P1 and the second portion P2 in the axial direction faces the end part of the image carrier 5 in the sheet metal member 9. The third portion P3 has a configuration such that an impedance between the third portion P3 and the image carrier 5 is higher than an impedance at least between the first portion P1 and the image carrier 5.SELECTED DRAWING: Figure 4 |
