Abstract
A cleanerless image forming apparatus and a cleanerless image forming method facilitate the collection of residual toners after image transfer. The image forming apparatus includes a rotary endless latent carrier, a rotary charging brush for charging the rotary endless latent carrier, and a unit for forming an electrostatic latent image on the rotary endless latent carrier. The electrostatic latent image is developed on the rotary endless latent carrier by supplying polymerization toners simultaneously with the cleaning of residual polymerization toners therefrom. The polymerization toners on the rotary endless latent carrier are then transferred to a sheet. The image forming method has a first operation of charging a rotary endless latent carrier; a second operation of forming an electrostatic latent image on the rotary endless latent carrier; a third operation of developing the electrostatic latent image on the rotary endless latent carrier by supplying polymerization toners simultaneously with cleaning residual polymerization toners therefrom; and a fourth operation of transferring the polymerization toners on the rotary endless latent carrier to a sheet.
