Abstract
An image forming apparatus for forming an image by developing a latent image formed on an image carrier, using a developer including a toner and a carrier. The image forming apparatus comprises: a developer conveying member that conveys the developer; a first collecting unit that collects, by generating a first electric field, the toner from the developer at a first position that is set halfway through a route of conveyance of the developer by the developer conveying member; and a second collecting unit that collects, by generating a second electric field, residual toner from the developer at a second position that is downstream of the first position in the route of conveyance of the developer.
