Abstract
A transfer unit includes a first and a second roller differing in one of the axial length, volume resistivity, and hardness of their elastic layer, a first and a second bearing members rotatably supporting the metal shafts of the first and second rollers, a roller holder, and a switching mechanism. The roller holder has a first and a second bearing holding portion that hold the first and second bearing members slidably. The switching mechanism drives the roller holder to rotate such that one of the first and second rollers is arranged at a reference position at which the first or second roller is kept in pressed contact with an image carrying member to form a transfer nip. The first and second bearing members have grounding member that ground the first and second rollers respectively.
