Abstract
A charging member has a conductive support, an elastic layer formed on the conductive support, and a tubing layer formed on the elastic layer. Fine particles are present between the tubing layer and a layer provided beneath the tubing layer is contact therewith.
Claims21
A charging member comprising a conductive support, an elastic layer formed on the conductive support, and a tubing layer formed on the elastic layer;
- fine particles being present between said tubing layer and a layer provided beneath said tubing layer in contact therewith;
- wherein said charging member is for use in electrophotography.
A process for producing a charging member comprising a conductive support, an elastic layer formed on the conductive support, and a tubing layer formed on the elastic layer;
- said process comprising the step of;
- forming said tubing layer on said elastic layer by inserting to the inside of a tubing a support having at least said elastic layer, after fine particles have been made or left to adhere to at least one of the surface on which said tubing layer is formed and the inner surface of the tubing;
- wherein said charging member is for use in electrophotography.
A process cartridge comprising a charging means having a charging member and an additional means selected from the group consisting of an electrophotographic photosensitive member, a developing means and a cleaning means;
- said charging member having an elastic layer on a conductive support and a tubing layer on the elastic layer;
- fine particles being present between said tubing layer and a layer provided beneath said tubing layer in contact therewith;
- and
- said charging member and said additional means being integrally supported in and detachable from the body of an electrophotographic apparatus.
