Abstract
An image forming apparatus having 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 and a spacer coupled to the charging member and configured to contact the image support body to maintain a gap between the image support body and the charging member. A cleaning part is configured to clean the surface of the image support body after developer is applied to the image support body and transferred to a recording medium. The cleaning part is 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.
