ELECTROPHOTOGRAPHIC COLOR PROCESS AND ELECTROPHOTOGRAPHIC LIGHT-SENSITIVE MATERIAL FOR USE IN THE TROPHOTOGRAPHIC COLOR PROCESS

摘要

An electrophotographic color process comprising the steps of: (a) charging an electrophotographic lightsensitive material by corona discharge, said material having at least two kinds of color-producing photoconductive particle disposed at random on an electroconductive support, said color-producing photoconductive particle consisting essentially of a photoconductive particle, a sensitizer and a leuco dye, (b) exposing said charged material to light,(c) developing said material by a toner containing an acid substance, and producing color in the leuco dye by the interaction of the leuco dye with the acid substance, and forming a color image by carrying out once the procedure of charging, exposing and developing. Also disclosed is an electrophotographic light-sensitive material comprising an electroconductive support and a photoconductive layer consisting of at least two kinds of colorproducing photoconductive particle disposed at random on the support, said color-producing photoconductive particle consisting essentially of a photoconductive particle, a sensitizer and a leuco dye.
