    摘要： Disclosed is a photoreceptor including a substrate, a charge generating layer, and a charge transport layer having a tertiary aryl amine charge transport molecule represented by the following general formula in which Ar1, Ar2, Ar3, Ar4 and Ar5 each independently represents a substituted or unsubstituted aryl group, or Ar5 independently represents a substituted or unsubstituted arylene group, and k represents 0 or 1, and in which at least two of Ar1, Ar2, Ar3 and Ar4 includes a hydroxymethyl group or an alkoxymethyl group having from 1 to about 6 carbon atoms, having an oxidation potential of from about 0.75 V to about 1.0 V as measured vs. Ag/AgCl in 0.1 M tetra-n-butylammonium perchlorate in dichloromethane, and an antioxidant capable of reacting with the charge transport molecule. Disclose is also a process for forming the photoreceptors described herein and a method of forming an image with the photoreceptors described herein.
