摘要： A crystalline phase of titanyl oxyphthalocyanine, referred to herein as the S-phase, has an internal blend of lattice arrangements is provided by treatment of the gamma-form of titanyl oxyphthalocyanine. The S-phase is a truly new phase, and not a mixture of particles of various phases (e.g., combinations of the beta-phase and the gamma-phase), with internal lattice distributions of atoms and molecules forming a new, non-continuous, non-uniform lattice structure. The x-ray spectrum shows a blend of diffraction peaks, having peaks that have previously been distinctly present only collectively among various crystalline forms of titanyl oxyphthalocyanine, but can now be provided in a single crystalline form. The visible spectra show significant absorption differences. The novel S-form titanyl oxyphthalocyanine is also used in a photoconductor displaying major peaks of Bragg's 2 theta angle to the CuK-alpha characteristic X-ray (wavelength 1.541 Angstrom) at least at 9.5±0.2 degrees, 9.7±0.2 degrees, 11.7±0.2 degrees, 13.5±0.2 degrees, (optionally at 21±0.2 degrees and/or 23.5±0.2 degrees,) 24.1±0.2 degrees, 26.4±0.2 degrees, and 27.3±0.2 degrees group. Additional peaks, approaching or equivalent to major peaks, may also be present as 15.0, 15.3 and 16.0±0.2 degrees.

摘要： An electrophotographic apparatus includes an electrophotographic photosensitive member comprising a support and a photosensitive layer thereon, a charging means for charging the photosensitive member, a multi-beam exposure means for illuminating the photosensitive member with a plurality of laser beams to form an electrostatic latent image on the photosensitive member, a developing means for developing the electrostatic latent image to form a toner image on the photosensitive member, and a transfer means for transferring the toner image from the photosensitive member to a transfer-receiving material. The electrophotographic apparatus is not equipped with a charge-removal means for uniformly charge-removing the photosensitive member in advance of operation of the charging means. Further, the photosensitive member has a photosensitive layer containing oxytitanium phthalocyanine and exhibits a charge mobility of 7.0×10−5 to 2.0×10−5 cm2/volt.sec. As a result, the electrophotographic apparatus can provide a higher process speed and/or a higher resolution because of the multi-beam exposure means without causing a density difference regardless of laser beam emission state.

摘要： A process for producing an electrophotographic photosensitive member has a layer. The process has the step of forming the layer by the use of a dispersion obtained by ejecting a pressurized fluid from an orifice into a hollow member having a diameter larger than the diameter of the orifice, to disperse a material to be dispersed. The fluid is ejected in substantially an unatomized state.

摘要： The present invention relates to an electrophotosensitive material wherein a layer containing a binder resin and a pigment among a photosensitive layer is formed by applying and drying a coating solution prepared by dispersing the binder resin and the pigment in a dispersion medium containing alcohol represented by the formula (1): wherein R1, R2 and R3 are the same or different and represent a hydrogen atom or an alkyl group; the electrophotosensitive material is free from lowering of the sensitivity due to formation of agglomerates of the pigment and is superior in sensitivity characteristics.

摘要： An electrophotographic photosensitive element is provided with a photosensitive layer containing a charge generating substance and a charge transport substance on a conductive support. X-type metal-free phthalocyanine and a disazo compound are contained as a charge generating substance. With the photosensitive element, sufficient sensitivity is achieved so as to cause virtually no problem, and it is possible to reduce possibility of causing an instable electrostatic property such as a reduction in a charge potential and an increase in a remained potential, even in the case of frequent reuse.
