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.
