Abstract: The charging device includes a charging roller, a bush and a case. The charging roller is configured to come into contact with or be close to a surface of an image carrier and configured to charge the surface of the image carrier. The bush is configured to support an end portion of the charging roller in a rotatable manner. To the case, the end portion of the charging roller is attached along a predetermined attachment direction by the bush. The case includes a pair of guide walls standing along the attachment direction so as to guide the bush. The bush includes a bearing part and a restriction part. The end portion of the charging roller is inserted into the bearing part. The pair of guide walls is put between the bearing part and the restriction part.

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.
