Title:
ELECTROCONDUCTIVE SUPPORT BODY AND METHOD FOR MANUFACTURING SAME, ELECTROPHOTOGRAPHIC PHOTORECEPTOR, AND ELECTROPHOTOGRAPHIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/077705
Kind Code:
A1
Abstract:
Provided are a high-precision electroconductive support body and a method for manufacturing the same, an electrophotographic photoreceptor with which high image quality is obtained by using the electroconductive support body, and an electrophotographic device using the electrophotographic photoreceptor. An electroconductive support body 1 for the electrophotographic photoreceptor, the electroconductive support body 1 comprising a cylindrical main body 11, a first end 12A of the main body in the length direction, and a second end 12B of the main body on the opposite side from the first end. The main body includes an aluminum alloy, the stress value of the main body being within the range of -30 MPa to 5 MPa inclusive. A method for manufacturing the electroconductive support body, the method comprising a preparation step for preparing a base that includes at least the aluminum alloy obtained via an extrusion step, and a heat treatment step in which the base is heat-treated and the electroconductive support body is obtained, the heat treatment being performed such that, when the temperature of the heat treatment is defined as T (°C) and time is defined as H (hours), a heat treatment amount Q defined as Q = T × H is at or below 800. The electrophotographic photoreceptor, comprising the electroconductive support body and a photosensitive layer formed on the base. The electrophotographic device, obtained by the electrophotographic photoreceptor being mounted.
