Abstract
An image forming method includes forming an image with a toner using a photoconductor in which an intermediate layer and a photosensitive layer including a charge generating layer and a charge transport layer are formed overlying an electroconductive substrate, wherein the ionization potential of the surface of the photoconductor and the ionization potential of the surface of the toner satisfy the following relations 1 and 2,|(the surface of the photoconductor)−(the surface of the toner)|≤5.53 (eV)   Relation 15.45 (eV)≤(the surface of the photoconductor)≤5.53 (eV)   Relation 2where Ip (the surface of the photoconductor) represents the ionization potential of the surface of the photoconductor and Ip (the surface of the toner) represents the ionization potential of the surface of the toner.
