IMAGE FORMING APPARATUS
First Claim
1. An image forming apparatus comprising:
- a charging member that moves;
a light source that includes a plurality of light source elements arranged at a predetermined arrangement pitch and that radiates charge-eliminating light toward the charging member;
a processing member that performs a process on a surface of the charging member at a position upstream or downstream of an irradiation region, in which the charging member is irradiated with the charge-eliminating light from the light source, in a direction in which the charging member moves;
a function member provided to enable the process of the processing member and disposed between the light source and the charging member at a position spaced from the light source, the function member facing a radiation path of the charge-eliminating light from the light source and extending in an arrangement direction in which the light source elements are arranged; 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 at which the light source elements are arranged and regions between the light source elements.

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.
