ABSTRACT:
An objective is to provide an image forming method and an image forming apparatus exhibiting neither failure in lack of line image nor image defect in halftone images, together with extremely high image quality and longer lifetime. Disclosed is an image forming method possessing the steps of evenly charging an organic photoreceptor; conducting a light exposure process; conducting a developing process to visualize the electrostatic latent image formed on the organic photoreceptor to form a toner image; transferring the toner image into a transfer medium; and conducting a cleaning process to remove a residual toner from the organic photoreceptor, the method further comprising the step of replenishing a developing device with a developer comprising toner and carrier, wherein the organic photoreceptor comprises a surface protective layer containing a filler, and the carrier is mixed with the toner, after attaching a lubricant onto a carrier particle in advance.
