In a cleaning-less image forming apparatus, an image forming apparatus that prevents charging failure of a latent image carrier due to adhesion of transfer residual toner to a charging member, and achieves both miniaturization, cost reduction, and improvement in image quality of the apparatus. I will provide a. A transfer efficiency is increased and a transfer residual toner is reduced by using a spherical toner having a charge control agent and / or organic fine particles present on a surface thereof. Of the transfer residual toner, collected at oppositely charged toner T 1 only brush roller 41, and discharged to the photosensitive drum 1 at a predetermined timing to transfer to the intermediate transfer belt 10. When passing through the oppositely charged toner T 1 is charged areas, or to stop the charging bias, or to separate the charging roller 3a from the photosensitive drum 1. [Selection diagram] FIG. |
