摘要:
An electrophotographic photoconductor including: an electrically conductive substrate; and at least a photoconductive layer on the electrically conductive substrate, wherein the electrophotographic photoconductor includes an uppermost surface layer, and the uppermost surface layer includes an inorganic filler, an acidic disperser and a three-dimensionally crosslinked polymer, wherein the three-dimensionally crosslinked polymer is 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, and wherein the polymerization proceeds after some of the [(tetrahydro-2H-pyran-2-yl)oxy]methyl groups have been partially cleaved and eliminated with an acid catalyst.
