PURPOSE:To improve the photosensitivity of the titled body, and to obtain the excellent stability and durability of the titled body at the time of iterative use by using a specified polyether ketone resin for the binder resin of an org. photoconductive layer. CONSTITUTION:The org. photoconductive layer is mounted on an electrically conductive supporting body. Said layer contains the polyether ketone resin as the binder resin, and said resin is composed from at least one kind of the unit selected from the repeating unit A1 shown by formula I and the repeating unit A2 shown by formula II, and at least one kind of the unit selected from the repeating unit B1 shown by formula III and the repeating unit B2 shown by formula IV, and has a structure of binding the repeating unit shown by formula I and the unit belonging to the repeating unit B alternately. In formula IV, R<1>-R<4> are each hydrogen atom or alkyl group, Y is a group sown by formulas V and VI, etc. (R<5> and R<6> are each hydrogen or methyl group, etc.). Thus, the high sensitivity and durability of the titled body are obtd. |
