Abstract
An image forming apparatus includes an image carrier, a removal roller, a collection roller, a housing, a screw, and a seal. The removal roller rotates while in contact with the intermediate transfer belt and removes residual toner from the intermediate transfer belt. The collection roller rotates while in contact with the removal roller so as to collect, from the removal roller by electrostatic force, waste toner that is the residual toner removed by the removal roller. The housing has an upper opening for receiving the waste toner collected by the collection roller and stores the waste toner. The screw conveys the waste toner stored in the housing. The seal comes into contact with the collection roller and closes a gap between the collection roller and the housing at the upper opening.
