摘要： There are described an image forming method and apparatus, which enable to form an electrophotographic image having high image density and excellent color reproducibility. The method includes: applying a uniform surface potential to an organic photoreceptor; irradiating light, having a wavelength in a range of 350-500 nm, on the photoreceptor, to form a latent image on the photoreceptor; and contacting a developing blush, containing toner and carrier, with the organic photoreceptor so as to form a visible toner image. The developing sleeve bears developing agent including the toner and the carrier. An absolute value of an electric charge potential of non-exposed area on the organic photoreceptor is in a range of 250-450 Volts and the developing sleeve is rotated in a counter direction, being counter to a rotating direction of the organic photoreceptor.
