|20090136260||ELECTROPHOTOGRAPHIC PHOTOCONDUCTOR AND ELECTROPHOTOGRAPHIC APPARATUS - An electrophotographic photoconductor including a conductive support and a photosensitive layer, wherein the photosensitive layer contains a charge generation agent, a charge transport agent and a binder resin, and wherein the charge generation agent contains an asymmetric disazo pigment represented by General Formula (I), the charge transport agent contains a triphenylamine compound represented General Formula (IX), and the mass ratio of the charge transport agent to the binder resin is 0.3 to 2.0,||05-28-2009|
|20090004585||ELECTROPHOTOGRAPHIC PHOTORECEPTOR AND ELECTROPHOTOGRAPHIC APPARATUS - An electrophotographic photoreceptor which can respond to a reduction in diameter of photoreceptor and a process having high circumferential speed, due to the demand in the miniaturization and increase in the speed of copiers and printers. The photoreceptor has high sensitivity in long-wavelength region, and is free from deterioration of electric characteristics even after repeated use, and is highly stable. The electrophotographic photoreceptor has a conductive support member and a photosensitive layer laminated thereon, which includes at least a charge-generating agent, a charge-transfer agent, and a binder resin. The charge-generating agent is oxytitanium phthalocyanine, which has a Bragg angle (||01-01-2009|
