PURPOSE:To provide high photosensitivity in the wavelength range of 520-900nm and to enable use by positive corona charge by forming a photosensitive layer contg. alpha-titanylphthalocyanine (TiOPc) dispersed in a binder. CONSTITUTION:A photosensitive layer contg. alpha-TiOPc dispersed in a binder is formed. It is preferable that the alpha-TiOPc shows strong peaks at 7.5 deg., 12.3 deg., 16.3 deg., 25.3 deg. and 28.7 deg. Bragg angle 2theta in the X-ray diffraction diagram. A superior P-type sensitive body having high sensitivity in the wide wavelength range of 520-900nm can be obtd. by forming the photosensitive layer. The sensitive body is suitable for use in a laser beam or liq. crystal printer using a light source emitting light of 700-900nm, and it is also used in an optical recording device using a light source emitting light of 750-850nm such as semiconductor laser. |
