Abstract
The present invention is directed to a silicon-containing triarylamine compound represented by the formula (1): ##STR1## wherein Q.sub.2 and Q.sub.3 independently represent a hydrogen atom or --CH.sub.2 SiR.sub.1 R.sub.2 R.sub.3 group (R.sub.1, R.sub.2 and R.sub.3, which may be identical or not, independently represent an alkyl group, cycloalkyl group, aralkyl group or aryl group which may be substituted); Ar.sub.1, Ar.sub.2 and Ar.sub.3 independently represent an arylene group which may be substituted; Q.sub.1 represents a --CH.sub.2 SiR.sub.1 R.sub.2 R.sub.3 group, --CH.sub.2 SiR.sub.1 R.sub.2 R.sub.4 group (R.sub.4 represents the following: ##STR2## wherein Q.sub.2 and Q.sub.3 independently represent a hydrogen atom) or --CH.sub.2 SiR.sub.1 R.sub.4 R.sub.4 group, a method of its production and a photoreceptor for electrophotography incorporating it as a charge transport material. The photoreceptor is very excellent in sensitivity and durability.
