Abstract:
An image forming apparatus includes a corona charger including a discharging wire, a grid electrode, for charging a photosensitive drum at a charging position; and an exposure device for exposing the drum charged by the charger at an exposure position which is in a downstream side of the charger in a rotational direction of the drum at the charging position. The grid electrode includes a first portion having openings and a second portion having only a non-opening portion in a charging region for charging the drum in a longitudinal direction of the charger, and the second portion includes a downstream side peripheral portion at a downstream end of the grid electrode with respect to the rotational direction. In a cross-section orthogonal to the longitudinal direction and including the charging region, the downstream side peripheral portion is intersected by a straight line passing through the exposure position and the wire.

Claim (Index 3):
An image forming apparatus according to  claim 1 , wherein the second portion includes an upstream side peripheral portion at an upstream end of said grid electrode with respect to the rotational direction, and a length of the downstream side peripheral portion measured in the rotational direction is larger than a length of the upstream side peripheral portion measured in the rotational direction.
