FLANGE FOR ELECTROPHOTOGRAPHIC PHOTORECEPTOR, METHOD FOR MANUFACTURING ELECTROPHOTOGRAPHIC PHOTORECEPTOR WITH FLANGE, AND ELECTROPHOTOGRAPHIC PHOTORECEPTOR WITH FLANGE

摘要

PROBLEM TO BE SOLVED: To provide a flange for electrophotographic photoreceptor which withstands various temperature environments, and to provide an electrophotographic photoreceptor provided with the flange and a manufacturing method thereof.;SOLUTION: The electrophotographic photoreceptor use flange 1 fitted to at least one opening of the electrophotographic photoreceptor constituted by forming a photoreceptive layer on a cylindrical base material is made of a material essentially consisting of a resin having the linear expansion coefficient of 3.0×10-5 cm/cm/°C to 5.0×10-5 cm/cm/°C. Metal is generally used as the cylindrical base material in the electrophotographic photoreceptor. In this case, when the flange 1 is fitted to the opening of the cylindrical base material, the fall-off of the flange 1 from the cylindrical base material is sufficiently prevented in low temperature, and the deformation of the cylindrical base material due to the excessive expansion of the flange 1 is sufficiently prevented in high temperature.;COPYRIGHT: (C)2001,JPO
