Image forming apparatus

An image forming apparatus configured to form an image on a recording material, the image forming apparatus comprising:

• a photosensitive member;
• a charging device configured to charge the photosensitive member by a charging bias being applied to the charging device;
• an exposure device configured to expose the photosensitive member which has been charged by the charging device to light to form a latent image on the photosensitive member;
• and
• a developer carrying member which carries a developer and which is configured to develop the latent image with the developer by a developing bias being applied to the developer carrying member,
• wherein, when it is assumed that an image forming area, a printing portion and a non-printing portion are an area on the photosensitive member on which an image to be transferred onto a recording material is formed, an area in the image forming area to which the developer carrying member makes the developer adhere and an area in the image forming area to which the developer carrying member does not make the developer adhere, respectively, the exposure device exposes the printing portion in the image forming area at a first laser power, exposes the non-printing portion in the image forming area at a second laser power smaller than the first laser power, and exposes a non-image forming area on the photosensitive member between two adjacent image forming areas at no laser power or a third laser power smaller than the second laser power.
