REUSABLE PHOTORECEPTOR, IMAGE FORMING DEVICE USING THE SAME, AND METHOD FOR DIAGNOSING SERVICE LIFE OF RECYCLABLE PHOTORECEPTOR

摘要

PROBLEM TO BE SOLVED: To provide a reusable photoreceptor reusable at a low cost. SOLUTION: In the reusable photoreceptor (photoreceptor 2) whose surface is regenerated by grinding so as to reuse the photoreceptor, when the thickness of a photosensitive layer abraded by image forming operations is represented by A, the thickness of a ground layer by B, the number of times of regeneration by (n) and the thickness of an original photosensitive layer by C, the formula C-[(A+B)n+A]>=10 μm is satisfied.
