Abstract:
1. An image forming apparatus comprising: an image support body configured to support a latent image; a charging member configured to provide a substantially uniform charge to a surface of the image support body; a spacer coupled to said charging member and configured to contact said image support body to maintain a gap between the image support body and the charging member; an exposing part configured to expose the charged surface of the image support body to write the latent image based on image data; a developing part configured to develop the latent image by supplying toner particles to the latent image formed on the surface of the image support body to make the latent image a visible image; a transferring part configured to transfer the visible image on the surface of the image support body onto a transferring medium; a cleaning part configured to clean the surface of the image support body after the transferring, said cleaning part being configured to satisfy the relationship A+B≦C, where A is a width of the effective charging area of the charging member that charges a surface of the image support body, B is a total width of the spacer that contacts the image support body, and C is a width of cleaning part that contacts the image support body; and a lubricant applying part configured to apply a lubricant to the surface of the image support body, wherein the relationship A+B≦E≦C is satisfied, where E is a width of lubricant applying part that applies a lubricant to the surface of the image support body.
