Abstract: A charging device includes a first charging unit and a second charging unit. The first charging unit electrostatically charges a surface of an image bearing member that comes into contact with a medium onto which an image is to be ultimately transferred. The first charging unit is disposed in correspondence with an entire region of the image bearing member in a first scanning direction. The second charging unit is disposed in an overlapping region where a non-passing region of a small-width medium and a passing region of a maximum-usable-width medium overlap when viewed in the first scanning direction. The small-width medium has a width smaller than a maximum usable width of the maximum-usable-width medium. The second charging unit electrostatically charges the overlapping region.

Abstract: An image forming apparatus includes a charging member; a light source that includes light source elements and that radiates charge-eliminating light toward the charging member; a processing member that performs a process on the charging member; a function member provided to enable the process of the processing member and disposed between the light source and the charging member, the function member facing a radiation path of the charge-eliminating light and extending in an arrangement direction of the light source elements; and an adjusting portion formed on a surface of the function member that faces the radiation path, the adjusting portion adjusting an amount of irradiation of the charging member by the charge-eliminating light so as to reduce a difference in the amount of irradiation between regions corresponding to arrangement positions of the light source elements and regions between the light source elements.
