Abstract
An organic photoreceptor that includes: PA1 (a) a charge transport compound having the formula ##STR1## where n is an integer between 2 and 6, inclusive; R.sup.1 and R.sup.2, independently, are an alkyl group, a cycloalkyl group, or an aryl group, or R.sup.1 and R.sup.2 combine with the nitrogen atom to form a ring; PA2 Y is a bond, a carbon atom, a --CR.sup.3 group, an aryl group, a cycloalkyl group, or a cyclosiloxyl group; PA2 R.sup.3 is hydrogen, an alkyl group, or an aryl group; and PA2 X is a linking group having the formula --(CH.sub.2).sub.m -- where m is an integer between 4 and 10, inclusive, and one or more of the methylene groups is optionally replaced by an oxygen atom, a carbonyl group, or an ester group; PA1 (b) a charge generating compound; and PA1 (c) an electroconductive substrate.
