Abstract
An image forming apparatus includes as photoconductive drum, a developing device for developing an electrostatic latent image on the drum with toner and simultaneously removing residual toner particles from the drum, and a transfer unit for transferring the developed image onto a recording medium. A distributing unit is arranged between the transfer unit and the developing device. The distributing unit temporarily attracts the untransferred toner particles remaining on the drum and then releases the attracted toner particles onto the drum, thereby distributing an untransferred toner image on the drum. Recording mediums are fed through a position between the drum and the transfer unit, with such an interval maintained between any two adjacent recording mediums, that the distributing unit is able to fully release the attracted toner particles onto the drum.
