Image forming apparatus, medium processing apparatus, and image forming method

Abstract

According to one embodiment, an image forming apparatus includes a retaining roller, a triboelectric charging device, and an inkjet head. The retaining roller includes a first charging section including a first dielectric and a second charging section including a second dielectric, which have different triboelectric charging characteristics, alternately on the surface of the retaining roller, retains a recording medium on the surface, and rotates. The triboelectric charging device charges the surface of the retaining roller by friction. The inkjet head forms an image on the recording medium retained on the surface of the retaining roller.
