ABSTRACT:
An image forming apparatus includes a photosensitive body. A charge member is held in contact with the photosensitive body and charges the photosensitive body by applying a voltage thereto. An exposure device exposes a surface of the photosensitive body charged by the charge member and forms an electrostatic latent image. A developing device attaches toner to the electrostatic latent image on the photosensitive body and visualizes the electrostatic latent image. Further, a particle diameter of fine powder which is the toner used in the developing device is equal to or less than 3 .mu.m, and a containing rate of the fine powder is equal to or less than 5%. Further, an angle of spatula of the toner used in the developing device may be at least 25 degrees. A cohesiveness of the toner may also be at least 9%.
