The present invention provides an image forming apparatus which can, by uniformly leveling the particles which are non-uniformly adhered to the surface of the photoconductor by using a leveling means having a predetermined shape, and can maintain the excellent image characteristics for a long period even when a contact charging method is adopted as a charging means and an image forming method which uses the image forming apparatus. In an image forming apparatus which sequentially arranges a charging means, a developing means, a transferring means and a charge eliminating means around an electrophotographic photoconductor, the charging means is constituted of a contact-type charging means, and a leveling means which levels particles on a surface of the electrophotographic photoconductor is arranged between the transferring means and the charge eliminating means.
