PROBLEM TO BE SOLVED: To provide an image formation device that can simultaneously solve problems of an edge surface contamination when a rear end of a recording medium passes through a conveyance guide plate, a location deviation of the recording medium due to a warp of the conveyance guide plate, and charge of the recording medium thanks to rubbing of the recording medium with the conveyance guide plate.SOLUTION: A conveyance guide plate 44 conveying a sheet to a secondary transfer nip part where a secondary transfer roller 21 abuts on an intermediate transfer belt 10 is formed of an electric zinc plating steel sheet, and is grounded. An upstream part 44a of the conveyance guide plate 44 parallely extends to a surface of the intermediate transfer belt 10, and an end part 44b thereof on a downstream side is folded in a direction separating from the intermediate transfer belt 10. Thus, toner 50 of the intermediate transfer belt 10 adheres to the upstream part 44a, and is hard to adhere to the downstream end part 44b and an end surface 44b-1. Even when a rear end of the sheet jumps like rubbing the end surface 44b-1 upon passing through the conveyance guide plate 44, the toner is not adhered, so that an edge surface contamination is not caused.SELECTED DRAWING: Figure 2 |
