PURPOSE:To obtain an electrophotographic sensitive body having stable initial potential, small dark attenuation, and high ozone resistance and abrasion resistance by incorporating a specified 1,4-dihydrotetrazine compd. into a charge transfer layer. CONSTITUTION:The title electrophotographic sensitive body is constituted of an electroconductive base body, a charge generating layer, and a charge transfer layer as essential constituting elements, and a 1,4-dihydrotetrazine compd. specified by the formula is incorporated into the charge transfer layer. In the formula, each R1 and R2 may be same or different to each other, being a (un) substituted alkyl or (un)substituted aralkyl group, or both may combine to form a ring together with an adjacent N atom; R3 is an H atom, (un)substituted aralkyl group, or (un)substituted heterocyclic group. Thus, an electrophotographic sensitive body having stable initial potential, small dark attenuation, and high ozone resistance and abrasion resistance, is obtd. |
