摘要： An electrophotographic photoreceptor which is excellent in the cleaning property and does not deteriorates the image quality for the formed images during long time use, and capable of forming images at high sensitivity, high resolution and high image quality, is provided. A photosensitive layer provided on a conductive substrate of an electrophotographic photoreceptor contains an oxotitanium phthalocyanine of a crystal form showing a diffraction peak at least at 27.3° in view of the Bragg angle 2θ in the X-ray diffraction spectrum and a surface free energy (γ) on a surface thereof is set to range from no less than 20 mN/m to no more than 35 mN/m. Such a inclusion of the oxotitanium phthalocyanine of specified crystal form enables formation of an image excellent in sensitivity and resolution and the control of a foreign matter depositing force when γ is set to an appropriate range, thus delivering a good cleaning performance.
