The present invention provides an organophotoreceptor comprising an electrically conductive substrate and a photoconductive element on the electrically conductive substrate, the photoconductive element comprising:
(a) a charge transport material having the formula
where R1, R2, R3, R4, and R5 are, independently, an alkyl group, an alkaryl group, an aryl group, or a heterocyclic group;
R6 and R7 are, independently, hydrogen, an alkyl group, an alkaryl group, an aryl group, or a heterocyclic group;
Y is a linking group having the formula -(CH2)m-, branched or linear, where m is an integer between 1 and 20, inclusive, and one or more of the methylene groups is optionally replaced;
X comprises an aromatic group, such as an aryl group or an aromatic heterocyclic group; and
Z comprises an arylamine group, such as a carbazole group, a julolidine group, or an (N,N-disubstituted)arylamine group; and
(b) a charge generating compound.
Corresponding electrophotographic apparatuses and imaging methods are described.
