    摘要: A new crystalline form of oxytitanium phthalocyanine is characterized by main peaks specified by Bragg angles (2.theta..+-.0.2 degrees) of 7.4 degrees, 10.2 degrees, 12.5 degrees, 15.0 degrees. 16.3 degrees, 18.3 degrees, 22.4 degrees, 24.2 degrees, 25.2 degrees and 28.5 degrees in X-ray diffraction pattern based on CuK.alpha. characteristic X-rays. The oxytitanium phthalocyanine is formed by treating amorphous oxytitanium phthalocyanine with a solvent selected from the group consisting of monohydric alcohols having at least two carbon atoms, cellosolves, diethylene glycol monoethers and diacetone alcohol. The oxytitanium phthalocyanine is useful as a charge generating material for providing an electrophotographic photosensitive member, which shows a stably high sensitivity to long wavelength light.

    摘要: An electrophotographic photosensitive member has a conductive support, and a charge generating layer and a charge transporting layer. The charge generating layer contains an acetal resin obtained from a reaction of polyvinyl alcohol, alkyl aldehyde having a structure shown in Formula (1) below, and aryl aldehyde having a structure shown in Formula (2) below:R--CHO (1)wherein R is a substituted or unsubstituted, chain or cyclic alkyl group, andAr--CHO (2)wherein Ar is a substituted or unsubstituted aryl group. The electrophotographic photosensitive member is used in electrophotographic apparatus, device units and facsimile machines, while ensuring superior electrophotographic characteristics and an excellent image free from fog.

    摘要: An electrophotographic photosensitive member is constituted by disposing a photosensitive layer on a support. The photosensitive layer is characterized by containing a specific triphenylamine compound having at least two phenyl groups each substituted with two alkyl groups including one alkyl group located in meta-position in conjunction with nitrogen atom or each substituted with three alkyl groups. The photosensitive member is suitable for providing an electrophotographic apparatus showing excellent electrophotographic characteristics such as a high photosensitivity, a good potential stability in repetitive use, a decreased transfer memory, no crack in the photosensitive layer and no crystallization of a charge-transporting material.
