A recycle developer bearing body which is an effective recycle of a used developer bearing body, helps effective utilization of resources, and does not result in image quality degradation, such as developer concentration unevenness. In the recycle developer bearing body, even when scars or other defects are developed on a developer bearing surface of the developer bearing body from previous use, a surface roughness Ra of the developer bearing surface having the scars or other defects of the developer bearing body is 0.8 &#x3bc;m or more.

Recycle developer bearing body, inspection method and inspection device thereof, method of recycling a developer bearing body, and method of recycling a used process cartridge

A method for regenerating a charging member for an electrophotographic system that is pressed against a surface of a body to charge the body, a charging member and a device for regenerating a charging member are provided. The method includes a step of applying heat treatment to the charging member. A used charging member, whose resistance is not decreased enough to recover a required chargeability by cleaning the surface thereof, can easily be regenerated and reused.

Method for regenerating charging member, charging member and device for regenerating charging member

The invention provides a washing method for a charging member by removing the deposited substance on the surface, thus making the charging member reusable. The washing method, for an electrophotographic charging member to be pressed to the surface of a member to be charged thereby charging the member to be charged, has a step of washing the surface of the charging member at least once with an acidic aqueous solution.
