ABSTRACT:
An electrophotographic photoconductor is composed of an electroconductive support, and a photoconductive layer formed thereon which contains as a photoconductive material at least one diamine compound having carbonate groups of formula (I): ##STR1## wherein R.sup.1 and R.sup.2 each is hydrogen, an alkyl group, or an aryl group; R.sup.1 and R.sup.2 may form a ring in combination of N bonded thereto; Y is an arylene group, ##STR2## wherein Ar.sup.1 and Ar.sup.2 each is an arylene group, R.sup.3 and R.sup.4 each is hydrogen, an alkyl group, or an aryl group, and l is an integer of 1 or 2; and R.sup.1 and Y may together form a ring, X is an alkylene group, a dialkylene ether group or an arylene group, --Ar.sup.3 -Z-Ar.sup.4 --, wherein Ar.sup.3 and Ar.sup.4 each is an arylene group; Z is an alkylene group, a dialkylene ether group or a cycloalkylidene group, oxygen, sulfur, a vinylene group, m is an integer of 0 or 1; and n is an integer of 0 to 6.
