PURPOSE:To prevent the delay of rise of potential by electrification after repeated use by forming at least an electric charge generating layer and an electric charge transferring layer on an electrically conductive support and incorporating a specified electron accepting compd. into the electric charge generating layer. CONSTITUTION:When at least an electric charge generating layer 21 and an electric charge transferring layer 22 are formed on an electrically conductive support 11 to obtain a laminate type org. electrophotographic sensitive body, an electron accepting compd. represented by formula I is incorporated into the electric charge generating layer 21. In the formula I, Y is a group represented by formula II or III, etc. In the formulae I-III, R is alkyl, alkoxy or halogen and each of m, n, p, q, r and t is an integer of 0-4. High sensitivity is rendered to the resulting sensitive body, the deterioration of the electrostatic chargeability due to fatigue by pre-exposure is remarkably reduced and the delay of rise of potential by electrification can be prevented even after repeated electrification and exposure. |
