| 20110091799 | ELECTROPHOTOGRAPHIC PHOTORECEPTOR AND MANUFACTURING METHOD THEREFOR - In an electrophotographic photoreceptor having a photosensitive layer on an electroconductive substrate, the photosensitive layer is a positive-charging laminate comprising at least a charge transport layer and a charge generating layer laminated in that order, with the charge generating layer containing at least a resin binder, a charge generating agent, a space filler and an electron transport agent, while the charge transport layer contains at least, as a resin binder, polystyrene and a hole transport agent, and mineral oil of the charge transport layer is in an amount of 1% by mass or less of an amount of polystyrene. Thus, a highly durable and economic positive-charging multilayer electrophotographic photoreceptor and a manufacturing method therefor may be achieved. | 04-21-2011 |
| 20130022902 | ELECTROPHOTOGRAPHIC PHOTORECEPTOR, IMAGE FORMING METHOD AND APPARATUS, AND PROCESS CARTRIDGE - An electrophotographic photoreceptor including an electroconductive substrate; a charge generation layer located overlying the electroconductive substrate; a charge transport layer located overlying the charge generation layer; and an outermost layer located overlying the charge transport layer. The charge transport layer includes a positive hole transport material having the following formula (1): | 01-24-2013 |
| 20150064614 | HIGH SPEED CHARGE TRANSPORT LAYER - A photoreceptor includes a substrate a charge generating layer disposed on the substrate and a charge transport layer disposed on the charge generating layer, the charge transport layer includes a hole transport molecule, a fluorinated diol, and a leveling agent, the charge transport layer is substantially free of a polymer binder and catalyst, and has a post-discharge voltage of less than about 10 volts. | 03-05-2015 |
| 430580450 | Additional nitrogen attached indirectly to the hydrazone group by nonionic bonding | 3 |
| 20090011349 | Photoreceptor for Electrophotography - An object of the invention is to provide a photoreceptor for electrophotography which has a low residual potential in an initial stage, is inhibited from increasing in residual potential, is prevented from decreasing in charge potential, undergoes little fatigue deterioration even upon repeated use, and is less apt to pose a problem concerning toxicity or environmental pollution. The invention relates to a photoreceptor for electrophotography which has a photosensitive layer containing an aromatic hydroxycarboxylic acid metal complex represented by the following general formula (1): | 01-08-2009 |
| 20100104964 | PHOTORECEPTOR FOR ELECTROPHOTOGRAPHY - An object of the invention is to provide a photoreceptor for electrophotography which has a low residual potential in an initial stage, is inhibited from increasing in residual potential, is prevented from decreasing in charge potential, and undergoes little fatigue deterioration even upon repeated use. The invention relates to a photoreceptor for electrophotography which has a photosensitive layer containing a cyclic phenol sulfide represented by the following general formula (1): | 04-29-2010 |
| 20150378269 | HYDRAZONE DERIVATIVE OF TRIPHENYLAMINE AND ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER - A hydrazone derivative of triphenylamine is represented by general formula (1). | 12-31-2015 |
