METHOD OF MANUFACTURING LAMINATION TYPE ELECTROPHOTOGRAPHIC PHOTORECEPTOR AND METHOD OF DISPLAYING PRODUCTION LOT

摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing a lamination type electro photographic photoreceptor and a method of displaying production lot capable of displaying production lot display direct on a photoreceptor drum and easily confirming the lot display without disturbing the automization of the photoreceptor drum and preferable in the view point of cost down. SOLUTION: At the time of laminating an under layer, a charge generating layer and a charge transfer layer successively on a conductive substrate, one of the distances from the end part of the substrate to respective layers is changed for every production lot.
