Layered electrophotographic photoconductors using chloroindium chlorophthalocyanine have been investigated. An evaporated film of chloroindium chlorophthalocyanine has a broad and strong light absorption band in the visible to near-infrared region and its crystal structure is very stable. The photoconductor using chloroindium chlorophthalocyanine as a carrier generation layer and polyvinylcarbazole as a carrier transport layer is highly sensitive in a wide spectral region (500–900 nm) without any special treatment during its preparation. The typical value of sensitivity is 2.5 cm2/μJ at 800–900 nm, so that this photoconductor is most suitable for a laser printer equipped with a AlGaAs laser diode.
