Abstract:
1. A charging device comprising: a discharge electrode that extends along a rotational axis direction of a member to be charged that rotates and has an arc-shaped outer peripheral surface, the discharge electrode being arranged to face the outer peripheral surface; a potential control plate arranged between the outer peripheral surface of the member to be charged and the discharge electrode and extending in the rotational axis direction of the member to be charged, the potential control plate being plastically deformed so as to independently maintain the shape of the potential control plate; and a support member that supports the potential control plate only at both end portions of the potential control plate in a long-side direction of the potential control plate, wherein the potential control plate is plastically deformed in an arc shape such that a curvature of the arc shape is larger than that of the member to be charged.
