PROBLEM TO BE SOLVED: To suppress the occurrence of an afterimage due to repeated printing and an increase in residual potential without increasing standby time.SOLUTION: An electricity eliminating/charging device comprises: a charging roller 42 in contact with a photoreceptor drum 41 to form a charging nip part N between the charging roller 42 and photoreceptor drum 41, the charging roller 42 charging the photoreceptor drum 41 in charging areas 44 and 45 formed on the upstream side and downstream side in the direction of travel of the photoreceptor drum 41 with respect to the charging nip part N; and an electricity eliminating lamp 43 that irradiates the charging areas of the photoreceptor drum 41 with electricity eliminating light to eliminate a charge on the photoreceptor drum 41, the electricity eliminating lamp eliminating electricity simultaneously in the charging areas 44 and 45. A charging roller cleaning roller 48 is formed of a material through which the electricity eliminating light 46 emitted from the electricity eliminating lamp 43 transmits, and the charging areas 44 and 45 are irradiated with the electricity eliminating light 46.SELECTED DRAWING: Figure 1 |
