Patent ID: 8092962

Claim:
An image forming apparatus comprising: one or a plurality of photosensitive members on which an electrostatic latent image is formed according to an image signal; a development mechanism for forming a toner image by developing the electrostatic latent images: and a transfer body to which the toner image is transferred, wherein the development mechanism includes a plurality of developing units holding toners comprising a first toner, a second toner to be transferred to the transfer body after the first toner, and a third toner to be transferred to the transfer body after the first and the second toners, wherein a second work of adhesion between the photosensitive member and the second toner is larger than a first work of adhesion between the photosensitive member and the first toner and a third work of adhesion between the photosensitive member and the third toner, wherein the second work of adhesion is not less than 102.0% and not more than 132.7% of the first work of adhesion.
