Patent ID: 7371497

Claim:
An image forming method, comprising: charging an electrophotographic photoreceptor; irradiating the electrophotographic photoreceptor to form an electrostatic latent image thereon; developing the electrostatic latent image with a toner to form a toner image thereon; and transferring the toner image onto a transfer sheet while applying an electric current not less than 65 μA to the electrophotographic photoreceptor, and controlling the electric current with a constant current controller, wherein the electrophotographic photoreceptor comprises: an electroconductive substrate; a charge generation layer disposed over the electroconductive substrate; and a charge transport layer disposed over the charge generation layer, wherein the charge generation layer comprises a titanylphthalocyanine crystal in the form of particles having an average primary particle diameter of 0.3 μm or less and having a CuKα 1.542 Å X-ray diffraction spectrum comprising plural diffraction peaks, wherein a maximum diffraction peak is observed at a Bragg (2θ) angle of 27.2°; main peaks are observed at 9.4°, 9.6° and 24.0°; and a minimum diffraction peak is observed at 7.3°; and no diffraction peak is observed at an angle greater than 7.3° and less than 9.4°, wherein said angles may vary by ±0.2° and the minimum interval where no peak is observed between required peaks at 7.3 and 9.4 is 2.0 degrees absolute or more, and wherein the charge transport layer is disposed on the charge generation layer by applying a solution of a charge transport material in a non-halide solvent on the charge generation layer.
