    摘要： An electrophotographic photoreceptor comprising a conductive substrate having thereon at least a subbing layer comprising an organometallic compound (e.g., organozirconium or organotitanium compound) and 3 to 30% by weight, based on the organometallic compound, of a compatible binder resin, a charge generating layer prepared by using a coating composition comprising hydroxygallium phthalocyanine crystals (preferably those having a novel crystal form) as a charge generating material, a binder resin, and a halogenated benzene as a dispersing medium, and a charge transporting layer in this order. The photoreceptor is excellent in sensitivity and stability on repeated use and is free from coating defects.

    摘要： Hydroxygallium phthalocyanine crystals having intense diffraction peaks at Bragg angles (2.theta..+-.0.2.degree.) of 7.5.degree., 9.9.degree., 12.5.degree., 16.3.degree., 18.6.degree., 25.1.degree. and 28.3.degree. in Cuk.alpha. characteristic X-ray diffractometry, a process for producing the same, and an electrophotographic photoreceptor containing the same are disclosed. The hydroxygallium phthalocyanine crystals are obtained by once preparing impurity-free hydroxygallium phthalocyanine having intense X-ray diffraction peaks at specific Bragg angles, followed by a solvent treatment for crystal transformation, in which the impurity-free crystals are prepared by using excess phthalocyanine ring-forming compound in the synthesis of starting gallium phthalocyanine or by removing insoluble matter from the acid paste of starting gallium phthalocyanine.

    摘要： An electrophotographic photoreceptor comprising a conductive substrate having provided thereon a photoconductive layer is disclosed, said photoconductive layer containing a high polymeric compound comprising a repeating unit comprised of a tetracarboxylic acid anhydride skeleton and a divalent organic group skeleton having an aromatic nucleus, said two skeletons being bonded via a nitrogen atom. Said high polymeric compound is formed by co-deposition of a tetracarboxylic acid anhydride compound and an aromatic diamine compound. The photoreceptor exhibits high sensitivity, high durability, and excellent image quality retention even when used repeatedly or in a high humidity environment.
