Interval holding mechanism of electrostatic image carrying body

Abstract

Abstract PURPOSE:To make it unnecessary to adjust a jig, and to reduce man-hour for assembly, and the number of parts, by providing a reinforcing member on both ends of an image carrying body, and forming the outside diameter of the press- contacted ends face part of the reinforcing member to be a butting member for holding an interval between an electrostatic image carrying body and an interval held device. CONSTITUTION:On both ends of a cylindrical drum 11 of an electrostatic image holding body which is made of a photosensitive body adhered onto a thin cylindrical circumferential surface made by an electro-forming method, a support ring 12 being a reinforcing member is provided, to made to press-contacted with an inside surface 11a of the drum and an end face 11b, and also an outside diameter 12b of the end face press-contacted part of the support ring 12 is formed to be a little larger than the drum diameter as a butting member. An interval held device 21 is made to press- contacted with the outside diameter 12b (the butting member) of the support ring 12, and since a space between the cylindrical drum 11 and the interval held device 21 is decided by providing a driven rotating member 22, a jig and adjustment are unnecessary, and the space is held with high accuracy.
