Patent ID: 7468230

Claim:
A wet-developing electrophotographic photoconductor which forms a photosensitive layer containing at least a charge generating agent, an electron transport agent, a hole transport agent and a binding resin on an electrically conductive base body thereof, wherein the binding resin contains a polycarbonate resin represented by a following general formula (1), and a molecular weight of the hole transport agent assumes a value which is equal to or more than 900, and an inorganic value/organic value (I/O value) of the electron transport agent is set to 0.60 or more, and an inorganic value/organic value (I/O value) of the binding resin is set to 0.37 or more; (R 1 to R 4 in the general formula (1) are respectively independent and represent a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group having 1 to 20 carbons, a substituted or unsubstituted aryl group having 6 to 30 carbons and a substituted or unsubstituted halogenated alkyl group having 1 to 12 carbons, and Λ represents —O—, —S—, —CO—, —COO—, —(CH 2 ) 2 —, —SO—, —SO 2 —, —CR 5 R 6 —, —SiR 5 R 6 — or —SiR 5 R 6 —O— (R 5 and R 6 are respectively independent and represent a hydrogen atom, a substituted or unsubstituted alkyl group having 1 to 8 carbons, a substituted or unsubstituted aryl group having 6 to 30 carbons, a trifluoromethyl group, or a cycloalkylidene having 5 to 12 carbons in which R 5 and R 6 form a ring and an alkyl group having 1 to 7 carbons may be included as a substituent group) and B represents single bond, —O— or —CO—).
