A photoreceptor regenerating apparatus for regenerating a photoreceptor for use in an image forming apparatus including a grinding member that grinds a surface of a used photoreceptor, a photoreceptor measuring device that measures a surface condition of the used photoreceptor, and a grinding condition setting device that sets grinding conditions of the grinding member according to a measurement value of the photoreceptor measuring device.

Photoreceptor regenerating apparatus and image forming apparatus using regenerated photoreceptor and method of regenerating photoreceptor

In a photoreceptor for an image forming apparatus including a charging device, a relationship between a thickness &ldquo;A&rdquo; of a surface portion of a photosensitive layer abraded by image forming operations, a thickness &ldquo;B&rdquo; of a portion of the photosensitive layer ground by an operation of grinding the abraded surface of the photosensitive layer, a number of times &ldquo;n&rdquo; the operation of grinding the abraded surface of the photosensitive layer has been executed, and an original photosensitive layer thickness &ldquo;C&rdquo; of the photoreceptor is set such that a thickness &ldquo;D&rdquo; of a remaining portion of the photosensitive layer after having been ground which is obtained by equation: D&equals;C&minus;&lsqb;(A&plus;B)&times;n&plus;A&rsqb;, 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.
