Abstract

In a photoreceptor for an image forming apparatus including a charging device, a relationship between a thickness “A” of a surface portion of a photosensitive layer abraded by image forming operations, a thickness “B” of a portion of the photosensitive layer ground by an operation of grinding the abraded surface of the photosensitive layer, a number of times “n” the operation of grinding the abraded surface of the photosensitive layer has been executed, and an original photosensitive layer thickness “C” of the photoreceptor is set such that a thickness “D” of a remaining portion of the photosensitive layer after having been ground which is obtained by equation: D=C−[(A+B)×n+A], is equal to or greater than a thickness of the photosensitive layer in which leakage from the charging device to the photoreceptor does not occur, so that the photoreceptor may be reused.
