Abstract
An image forming apparatus includes a transfer body that rotates and transfers a transferred image to a target transfer body at a transfer position, plural image holding members that rotate together with the transfer body at different positions along a rotation direction of the transfer body while outer peripheral surfaces of the image holding members come into contact with the transfer body, the image holding members on which a charge erasing operation is sequentially performed after images held on the outer peripheral surfaces sequentially transferred to the transfer body, and in which the charge erasing operation on all the image holding members has been ended, and then rotations of all the image holding members are stopped, a first charge erasing unit that erases charges of an outer peripheral surface of at least one image holding member other than a most downstream image holding member disposed on a most downstream side of the rotation direction with respect to the transfer position, among the plural image holding members, and a second charge erasing unit that erases charges of an outer peripheral surface of the most downstream image holding member and has a charge erasing time shorter than a charge erasing time of the first charge erasing unit.
