Electrophotographic photosensitive bodies which comprise a photosensitive layer on a conductive support, and which contain a wax having an ester group in their outermost layer, exhibit excellent durability and improved wear and printing resistance, without sacrificing their photosensitizability properties, such as chargeability and sensitivity, or ease and quality of application.

Electrophotographic photosensitive bodies

A device and method for reducing noise and/or vibration in an image forming apparatus. In a preferred form, an insert is disposed inside of a photosensitive drum, and the insert is a hollow tubular member including first and second members having surfaces oblique with respect to a longitudinal axis of the photosensitive drum, wherein the surfaces each face each other. The first and second members are moved relative to each other in order to change the overall diameter of the insert, such that upon insertion, the overall diameter can be made smaller than the inner diameter of the drum, and after insertion, the overall diameter of the insert can be increased such that the outer surface of the insert comes into contact with an inner surface of the drum. As such, the insert can be anchored to the interior of the drum without using adhesive and can be easily removed for recycling purposes.
