Abstract: The photoelectroconductivity of a double-layered photoreceptor (P/R) was studiedin the paper,in which the chloroinduim phthalocyanine(ClInPc)was a carrier gen-eration layer and polyvinyl carbazole (PVK) incoporating tetraphenyl benzidine (TPD) as,a carrier transportation layer. Results of the P/R consisting of ClInPc/PMMA (30%) matched with TPD/PVK (1:1) shows excellent protoelectronic properties:acceptance po-tential,V_max (800V);residual potential,V_min (30V/s);dark decay,RD (<50V/s);light dis-charge,△V_t (ls) >70%;half decay,t_1/2(ls)=0.30~0.53. Simultaneously the photoelectronicproperties of the P/R device in which the CGL is made by means of evaporating at vacuumare better than that of other method.
