摘要：
According to the present invention, a titanyl phthalocyanin crystal excellent in storage stability in organic solvents, a method for preparing the same and an electrophotographic photoconductor using the same are provided. In the titanyl phthalocyanin crystal, the method for preparing such a titanyl phthalocyanin crystal and the electrophotographic photoconductor using the same, the titanyl phthalocyanin crystal is characterized by having the maximum peak at a Bragg angle 2θ ± 0.2° = 27.2° in a CuKα characteristic X-ray diffraction spectrum and one peak within the range of 270 to 400°C other than a peak accompanied by the vaporization of adsorbed water in a differential scanning calorimetric analysis.
