Patent ID: 8268521

Claim:
An electrophotographic photoreceptor comprising: a conductive substrate; and a photosensitive layer provided on a surface of the conductive substrate, an outermost layer of the photosensitive layer containing a crosslinked product formed from at least one charge transporting material having at least one substituent selected from the group consisting of —OH, —OCH 3 , —NH 2 , —SH, and —COOH, an acidic substance, and at least one compound selected from the group consisting of compounds represented by the following formula (A) and compounds represented by the following formula (B): wherein, in formula (A), L 1 and L 2 each independently represent a substituted or unsubstituted alkyl group having 1 to 5 carbon atoms, or a substituted or unsubstituted aralkyl group having 7 to 15 carbon atoms; L 3 and L 4 each independently represent a substituted or unsubstituted alkyl group having 1 to 5 carbon atoms, a substituted or unsubstituted alkoxy group having 1 to 5 carbon atoms, or a substituted or unsubstituted aralkyl group having 7 to 20 carbon atoms; and f and g each independently represent 1 or 2; and wherein, in formula (B), L 5 to L 8 each independently represent hydrogen, a substituted or unsubstituted alkyl group having 1 to 5 carbon atoms, a substituted or unsubstituted alkoxy group having 1 to 5 carbon atoms, a substituted or unsubstituted aralkyl group having 7 to 15 carbon atoms, or a substituted or unsubstituted aryl group having 6 to 15 carbon atoms; at least one of L 5 to L 8 has a structure represented by the following formula (C); h to k each independently represent 1 or 2; and L 9 and L 10 each independently represent hydrogen, a substituted or unsubstituted alkyl group having 1 to 5 carbon atoms, a substituted or unsubstituted aralkyl group having 7 to 15 carbon atoms, or a substituted or unsubstituted aryl group having 6 to 15 carbon atoms: wherein, in formula (C), L 1 and L 2 each independently represent a substituted or unsubstituted alkyl group having 1 to 5 carbon atoms, or a substituted or unsubstituted aralkyl group having 7 to 15 carbon atoms.
