Abstract:
1. An image forming apparatus comprising: a photosensitive member; a charging unit configured to charge the photosensitive member by outputting a charging voltage; an exposure unit configured to form a latent image on the photosensitive member by irradiating the charged photosensitive member with light; a developing unit configured to develop the latent image on the photosensitive member with toner by outputting a developing voltage; and a control unit configured to cause the exposure unit to expose an image portion of the photosensitive member to which the toner is to be adhered by a first exposure amount, and expose a non-image portion of the photosensitive member to which the toner is not to be adhered by a second exposure amount smaller than the first exposure amount, wherein the control unit corrects the preset second exposure amount based on information about a difference between the charging voltage output from the charging unit and a predetermined charging voltage and/or information about a difference between the developing voltage output from the developing unit and a predetermined developing voltage.
