Patent ID: 7459256

Claim:
A method for forming an image, comprising: applying a uniform surface potential to an organic photoreceptor by a charging device; irradiating light having a wavelength in a range of 350 to 500 nm and emitted from a semiconductor laser or a light emitting diode which is equipped in an exposed device, on said photoreceptor, to form a latent image; and contacting a developing blush, which is formed on a developing sleeve and contains toner and carrier, with said photoreceptor having said latent image so as to form a visible toner image, wherein said developing sleeve is equipped in a developing device; wherein an absolute value of an electric charge potential of a non-exposed area residing on said organic photoreceptor is in a range of 250 to 450 Volts at an exposing position of said exposing device; and wherein said developing sleeve is rotated in a counter direction, being counter to a rotating direction of said organic photoreceptor.
