ABSTRACT:
Photoconductive zinc oxide characterized by having improved electrophotographic properties and particularly increased discharge speed, and produced by a process involving mixing the photoconductive zinc oxide powder to be improved with 0.01% by weight or more tellurium calculated as Te, and contacting the thus-obtained mixture with a free oxygen-containing gas while heating the mixture at elevated temperature sufficiently high and for a time sufficient to result in the zinc oxide having the improved electrophotographic properties. The heating temperature and/or heating time is held below that temperature or time at which sintering of the thus-treated product occurs.
