LIGHTTIGHT SHEET FOR CYLINDRICAL PHOTORECEPTOR FOR ELECTROPHOTOGRAPHY AND ITS DETACHING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a lighttight sheet for a cylindrical photoreceptor for electrophotography with which work for detaching a black sleeve from the photoreceptor is facilitated, stable image quality is obtained by preventing the damage of the photoreceptor and the efficiency of detaching work is improved. SOLUTION: Cutting and tearing work is performed to the lighttight sheet wound to protect the cylindrical photoreceptor for electrophotography so that the light shielding sheet can be cut and torn to be detached in the case of detaching the wound light shielding sheet.
