Patent Number: 7,785,762

Title: Image forming apparatus and image forming method

Abstract: An image forming apparatus including an image bearing member for bearing a latent electrostatic image including a substrate, an intermediate layer containing a metal oxide, a photosensitive layer including a charge transport layer and a charge generating layer containing an organic charge genetrating material, an image forming device for forming the latent electrostatic image on the image bearing member, a developing device for developing the latent electrostatic image with a toner to form a visualized image, a transfer device for transferring the visualized image to a recording medium, a fixing device for fixing the transferred image on the recording medium; and a discharging device including a light source that provides light having a wavelength shorter than 500 nm for optically discharging the image bearing member to remove remaining charges thereon by irradiating the image bearing member with light having a wavelength shorter than 500 nm which is absorbed by the metal oxide in the intermediate layer.
