ABSTRACT:
It is an object of the present invention to provide a wet-developing electrophotographic photoconductor which can be manufactured stably by making use of particular physical property indexes of an electron transport agent and a binding resin and possesses the excellent durability and the excellent solvent resistance and a wet-developing image forming device which uses such a wet-developing electrophotographic photoconductor. To achieve such an object, in 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 and a wet-developing image forming device which uses the wet-developing electrophotographic photoconductor, 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, or a molecular weight of the electron transport agent is set to a value equal to or more than 600 and an inorganic value/organic value (I/O value) of the binding resin is set to 0.37 or more.
