PRODUCTION OF CYLINDRICAL SUBSTRATE FOR ELECTROPHOTOGRAPHIC PHOTORECEPTOR

Japanese Patent JP3240874

B2

PURPOSE: To provide a method for producing plural cylindrical substrates for electrophotographic photoreceptors which consist of materials consisting essentially of plastic, allow good fitting and fixing of flanges at their both opening ends and vary in length sizes with one metal mold with good productivity.
CONSTITUTION: The plural cylindrical substrates for the electrophotographic photoreceptors varying in the length sizes are obtd. with one metal mold by molding substrates 1 which are cylindrical substrates 1 consisting of materials essentially consisting of plastic and having slopes on the inside surfaces and have the inside surfaces 2a to 2c, 3 having no slopes in parallel with the axial direction of the cylinder at both opening ends thereof by an injection molding method and cutting these substrates 1 at the points of at least one of the inside surfaces having no slopes, then cutting the substrates perpendicularly to the axis of the cylinder in the positions where the inside surfaces longer than the fitting parts of the flanges for rotational driving remain on the end sides of the substrates.
