New titanium oxide phthalocyanine polymorph, producing method thereof and method for producing organic photoconducting drum using thereof

摘要

The present invention relates to a process for their preparation oxide phthalocyanine, a new crystal form of titanium and a method of manufacturing an organic photosensitive drum for electrophotography using the same, and more particularly, XRD 2θ (degree) values ​​are 9.3, 10.5, 12.4, 13.1, 15.1 the present invention that relates to a production method of 15.6, 16.0, 20.7, 23.3, 26.2, 26.8 and 27.1 the organic photosensitive drum for electrophotography, characterized by a peak using a new crystal form of titanium oxide phthalocyanine, and this charge generating material may appear in the a light sensitivity that can provide excellent and at the same time a superior organic photoconductor drum cancer damping characteristic by.
