PURPOSE: To obtain an electrophotographic receptor high in stability against repeated uses, by laminating a carrier generating layer and a carrier transfer layer containing an amine derivative, a carbazole derivative, and a specified polymeric organic semiconductor on a conductive substrate.
CONSTITUTION: An electrophotographic receptor is formed by laminating on a conductive substrate a carrier generating layer and a carrier transfer layer containing an amine derivative of formulaI(Ar1, Ar2, Ar3 are each optionally substd. aromatic hydrocarbon or hetrocyclic group), such as a compound of formula II, a carbazole derivative of formula III (R1, R2 are each H, halogen, optionally substd. alkyl or alkoxy or aryl or amino or the like; R3, R4 are each optionally substd. alkyl or aryl; and Ar is optionally substd. divalent homo- or heterocyclic containing O or S), such as a compound of formula IV, and a polymeric organic semiconductor having a condensed aromatic ring, or hetero ring in the side chain, such as a compound of formula V.
