PURPOSE:To improve sensitivity and to extend the life of printing resistance by incorporating >=one kinds of specific compds. as an electric charge transferable material into a titled body. CONSTITUTION:The charge transferable material of the electrophotographic sensitive body contg. an electric charge generating material and the charge transferable material on a conductive base contains >=one kind of the compds. expressed by the formula I: X-(CH=CH)n-Ar. In the formula, X denotes a heterocyclic group; n denotes 0, 1 or 2; Ar denotes a substd. or unsubstd. aryl group. The lower ionization potential the higher ability to accept the electric charge from the charge generating layer and the better sensitivity and photosensitiveness are thereby obtd. and the chemical stability even in an oxidative atmosphere and decreased deterioration in long-term use are simultaneously obtd. |
