Abstract
A function separation type photoconductor for use in electrophotography comprises an electroconductive substrate, a carrier generation layer vapor deposited on the substrate and a carrier transport layer formed on the carrier generation layer. The carrier generation layer is made of an indium phthalocyanine having the general formula ##STR1## wherein Me represents indium, and X is a halogen selected from the group consisting of chlorine, bromine and iodine.
