    摘要： An electrophotographic article having a complex of charge generating material and at least one transfer material selected from the group consisting of electron transfer material and hole transfer material is formed by admixing the charge generating material, at least one transfer material, and an organic binder in a solvent to form a coatable dispersion comprising a complex of charge generating material and said at least one transfer material; and coating said coatable dispersion onto a conductive substrate to form a charge transfer layer on the electrophotoconductive article. A novel S-form titanyl oxyphthalocyanine is also preferred, the novel form displaying major peaks of Bragg's 2theta 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： 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.
