ABSTRACT:
An image forming apparatus, using a developer including toner particles and carrier particles, includes a developing unit, a cleaning unit, and a conveying unit. The developing unit contains the developer and develops an electrostatic latent image formed on an image carrying member as a toner image with the toner particles. The cleaning unit contains the developer and mixes the developer with the toner particles collected from the image carrying member after transferring the toner image. The conveying unit conveys a mixture of the collected toner particles and the developer from the cleaning unit to the developing unit.
