METHOD FOR MANUFACTURING CYLINDRICAL TUBE FOR ELECTROPHOTOGRAPHIC MEMBER, ELECTROPHOTOGRAPHIC MEMBER USING CYLINDRICAL TUBE FOR ELECTROPHOTOGRAPHIC MEMBER MANUFACTURED BY THE MANUFACTURING METHOD, ELECTROPHOTOGRAPHIC PHOTORECEPTOR, PROCESS CARTRIDGE, AND ELECTROPHOTOGRAPHIC DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a support for an electrophotographic photoreceptor by which a highly accurate cutting work can be efficiently carried out without tapering work or the like on the inside of a tube stock material of the support for an electrophotographic photoreceptor upon manufacturing the support, to provide an electrophotographic photoreceptor that gives a stable full-color image having no image defect such as color shift by using the support for an electrophotographic photoreceptor manufactured by the above manufacturing method, and to provide a process cartridge and an electrophotographic device into which the photoreceptor is incorporated.

SOLUTION: The method for manufacturing the support for the electrophotographic photoreceptor includes a step of cutting the outer circumference face of the tube stock to manufacture the support for an electrophotographic photoreceptor, wherein the outer circumference face is cut by using a holding tool which holds the tube stock at both ends, and portions holding the both ends of the tube stock of the holding tool are machined to conical faces. Relations of θ1<θ2 and 2<θ2/θ1<15 are satisfied, where θ1, θ2 are taper angles of the conical faces.
