Abstract

PURPOSE:To improve optical memory-optical fatigue of a dispersion type photosensitive agent of photoconductors/resins by adding polyester contg. specific glycol as a diol component into said agent. CONSTITUTION:In the electrophotographic photosensitive agent composition wherein >=1 kind of org. and inorg. photoconductive materials are dispersed in a reinforcing-binding medium consisting of an electrical insulation characteristic resin, the polyester[the one derived from 2, 2-bis(oxyethoxyphenyl)propane, etc.]contg. the glycol of the formula (Y is directly coupled-bivalent crosslinked atoms or groups; R is C2-4 alkylene; ring A may be substituted with halogen atoms) as a diol component in repetitive units is contained at 1-40wt% per electric insulation characteristic resin. The optical memory-optical fatigue of this photosensitive agent are considerably improved, and the electrophotographic material extremely suited for applications of repetitive copying is obtained.
