ABSTRACT:
The object of the present invention is to provide a photoconductor that is highly sensitive, stable in image quality under repeated usages, and affords prolonged life.In order attain the object, a photoconductor is provided that comprises a charge generating layer, a charge transporting layer, and a crosslinked charge transporting layer, on an substrate in order,the charge generating layer contains titanyl phthalocyanine crystal particles that exhibit a highest peak at 27.2°, main peaks at 9.4°, 9.6° and 24.0°, a peak at 7.3° as the lowest angle, and with no peaks in a range between 7.3° and 9.4°, and with no peak at 26.3° as Bragg 2θangles (±0.2°) in terms of CuK-α characteristic X-ray wavelength at 1.542 Å, and the averaged primary particle size of the titanyl phthalocyanine crystal particles is 0.25 μm or less, andthe crosslinked charge transporting layer contains a reaction product of a radical polymerizable monomer having three or more functionalities and no charge transporting structure and a radical polymerizable compound having one functionality and a charge transporting structure, and the thickness of the crosslinked charge transporting layer is 1 to 10 μm.
