ELECTROPHOTOGRAPHIC SYSTEM USING NO DRUM HEATER

摘要

PROBLEM TO BE SOLVED: To obtain a sharp image without image flow under high temperature and high humidity conditions without using a drum heater in a copying machine or a printer mounting an a-Si drum. SOLUTION: An electrostatic latent image developing toner prepared by externally adding a polish cleaning agent and silica fine particles to toner source powder having≤300 shape factor SF1 (degree of roundness) and≤250 shape factor SF2 (degree of ruggedness) is used in the electrophotographic system using an amorphous silicon photoreceptor. After the toner together with the polish cleaning agent particles are subjected to development, the toner is separated from the polish cleaning agent particles in the transfer process of the toner. No drum heater is used in the system. COPYRIGHT: (C)2004,JPO
