Abstract
A triphenylamine derivative, represented by the following general formula (1): ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and R.sup.6 each represents a hydrogen atom, a lower alkyl group, an alkoxy group, a halogen atom or an aryl group which may have a substituent group; and m and n each represents 0 or 1.
Claims6
An electrophotographic photoreceptor comprising a charge-transporting material comprising a triphenylamine derivative represented by the following general formula (I):
- ##STR50## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and R.sup.6 may be the same or different and each represent a hydrogen atom, a lower alkyl group, an alkoxy group, a phenoxy group, a halogen atom or an aryl group which may have a substituent group;
- and m and n each represents 0 or 1.
A lamination type electrophotographic photoreceptor comprising a charge-generating layer and a charge-transporting layer provided on an electrically-conductive support, characterized in that there is contained a charge-transporting material comprising a triphenylamine derivative represented by the following general formula (1):
- ##STR53## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and R.sup.6 may be the same or different and each represent a hydrogen atom, a lower alkyl group, an alkoxy group, a phenoxy group, a halogen atom or an aryl group which may have a substituent group;
- and m and n each represents 0 or 1.
A single-layer type electrophotographic photoreceptor comprising a charge-generating material and a charge-transporting material provided on an electrically-conductive support, characterized in that there is contained a charge-transporting material comprising a triphenylamine derivative represented by the following general formula (1):
- ##STR56## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and R.sup.6 may be the same or different and each represent a hydrogen atom, a lower alkyl group, an alkoxy group, a phenoxy group, a halogen atom or an aryl group which may have a substituent group;
- and m and n each represents 0 or 1.
