Abstract
The present invention relates to an image forming apparatus 1 including a photosensitive member 2 on which an electrostatic latent image is formed according to an image signal, a development mechanism 5 for forming a toner image by developing the electrostatic latent images, and a transfer body 60 for transferring the toner image. The development mechanism 5 includes a plurality of developing units 51-54 holding different kinds of toners. A second work of adhesion between the photosensitive member 2 and a second toner to be transferred to the transfer body second is larger than a first and a third work of adhesions between the photosensitive member 2 and a first and a third toners to be transferred to the transfer body first and third.
