PURPOSE:To obtain an electrophotographic receptor superior in sensitivity, durability, flexibility, etc., by forming a photosensitive layer contg. a specified hydrazone compd. on a conductive substrate. CONSTITUTION:The intended electrophotographic receptor is obtained by forming on a conductive substrate of an aluminum plate or the like, a photosensitive layer consisting of a hydrazone compd. having formula I (in which formula IIis a hydrocarbon or hetero ring each optionally substd., and R1, R2 are each hydrocarbon or hetero ring each optionally substd.), a binder, when needed, together with a sensitizing dye, an electron attractive compd., etc. Said hydrazone compd. of formula I is obtained, for example, by reacting a ketone compd. represented by formula III with a hydrazine compd. in ethyl alcohol in the presence of acetic anhydride as a catalyst under reflux. Embodiments of said hydrazone compds. are exemplified by compds. having formulae V, VI, etc. |
