Image forming apparatus having a photosenstive member of high capacitance

An image forming apparatus comprising:

• a photosensitive member, having a capacitance per unit area of 1.7×10−6 (F/m2) or larger;
• an exposure device, which exposes the photosensitive member to form an electrostatic image according to image information on the photosensitive member;
• a developing device, which develops the electrostatic image with a toner to form a toner image on the photosensitive member;
• a transfer device, which transfers the toner image onto a recording material;
• and
• an execution portion, which executes at least a mode of forming electrostatic images different in potential level on an image area of the photosensitive member on which an image corresponding to a maximum image density is to be formed, so that a toner bearing amount per unit area becomes a toner bearing amount corresponding to the maximum image density, when the image corresponding to the maximum image density is formed on the recording material.
