    摘要: An electrophotographic photoreceptor is provided comprising, in sequence:a) a conductive base;b) a carrier transport layer;c) a carrier generation layer comprising a selenium alloy;d) a carrier injection regulating layer having a band gap energy greater than that of the carrier generation layer and comprising selenium and up to about 10 weight % arsenic;e) a thermal expansion relieving layer comprising aresenic and selenium; andf) a surface protective layer comprising arsenic and selenium in an atomic ratio of approximately 2 to 3;wherein the arsenic concentration in the thermal expansion relieving layer gradually increases from a concentration substantially equal to that of the carrier injection regulating layer on a face of the thermal expansion relieving layer adjacent to the carrier injection regulating layer to a concentration substantially equal to that of the surface protective layer on an opposite face of the thermal expansion relieving layer adjacent to the surface protective layer. This structure eliminates or reduces damage to the photoreceptor caused by thermal stress when the carrier generation layer and the carrier injection regulating layer have greater thermal expansion coefficients than the As.sub.2 Se.sub.3 of the surface protective layer.

    摘要: A biphenyl derivative is included in a photosensitive layer of an electrophotographic photoconductor. The electrophotographic photoconductor includes a single-layer photosensitive layer coated on a conductive substrate. The photosensitive layer includes a resin binder, a charge generation substance, a hole transport substance, and an electron transport substance. An electrophotographic apparatus using such an electrophotographic photoconductor has excellent electrical characteristics in a positive chargine system and is stable in repeated use.
