ELECTROPHOTOGRAPHIC PHOTOCONDUCTOR, AND IMAGE FORMING METHOD, IMAGE FORMING APPARATUS, AND PROCESS CARTRIDGE USING THE ELECTROPHOTOGRAPHIC PHOTOCONDUCTOR

摘要

An electrophotographic photoconductor including: a conductive substrate; and at least a photoconductive layer on the conductive substrate, wherein an uppermost surface layer of the photoconductive layer includes a three-dimensionally crosslinked film formed through polymerization among compounds each containing a charge transporting compound and three or more [(tetrahydro-2H-pyran-2-yl)oxy]methyl groups where the charge transporting compound has one or more aromatic rings and the [(tetrahydro-2H-pyran-2-yl)oxy]methyl groups are bound to the aromatic rings of the charge transporting compound, wherein the polymerization starts after some of the [(tetrahydro-2H-pyran-2-yl)oxy]methyl groups have been partially cleaved and eliminated, and wherein the three-dimensionally cross-linked film has an ionization potential of 5.4 or higher.
