Patent ID: 8586270

Claim:
An electrophotographic photoconductor comprising: an electrically conductive substrate; and at least a photoconductive layer laid on the electrically conductive substrate, wherein the photoconductive layer contains a diazapentadiene derivative represented by the following general formula (1): in the general formula (1), “X” represents the following general formula (a), (b) or (c); “R 1 ” and “R 2 ” each represent a substituted or unsubstituted alkyl group or a substituted or unsubstituted aromatic hydrocarbon group, and may be the same or different; the “R 1 ” and “R 2 ” may be joined together via “Y” to form a ring; “Y” represents a single bond, an oxygen atom, —CH 2 CH 2 —, or —CH═CH—, in the general formula (a), (b) or (c), “R 3 ” represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted aromatic hydrocarbon group, a substituted or unsubstituted alkoxy group, an alkoxycarbonyl group, or a halogen group; “R 4 ” represents a substituted or unsubstituted alkyl group, or a substituted or unsubstituted aromatic hydrocarbon group; “n” represents an integer ranging from 0 to 4; and when “n” is an integer of 2 to 4, “R 3 ” may be the same or different.
