    摘要： The present invention relates to a titanylphthalocyanine represented by the formula (1):

    comprising a polymorph having a peak at a Bragg angle (2θ ± 0.2°) in X-ray diffraction spectrum with CuK α-ray: 9.0°, 9.6°, 14.1°, 14.9°, 17.9°, 18.3°, 23.4°, 24.5° and 27.2°; and



    and

    wherein
    I r1 is the ratio (9.6°/9.0°) of the intensity of the peak at Bragg angle of 9.6° to the intensity of the peak at Bragg angle of 9.0°;
    I r2 is the ratio (14.1°/14.9°) of the intensity of the peak at Bragg angle of 14.1 ° to the intensity of the peak at Bragg angle of 14.9°;
    I r3 is the ratio (17.9°/18.3°) of the intensity of the peak at Bragg angle of 17.9° to the intensity of the peak at Bragg angle of 18.3°; and
    I r4 is the ratio (24.5°/23.4°) of the intensity of the peak at Bragg angle of 24.5° to the intensity of the peak at Bragg angle of 23.4°.
    The present invention can provide the above novel titanylphthalocyanine having superior photoreceptor characteristics, particularly superior chargeability and photosensitivity to those of the conventional titanylphthalocyanines, and a method for producing the present titanylphthalocyanine, as well as an electrophotographic photoreceptor comprising a charge generating material of the present titanylphthalocyanine, which has excellent photosensitive characteristics.
