A transfer roller drive unit sets an all-separate mode after setting a full-color mode, sets a monochrome mode after setting the all-separate mode, and sets a full-color mode after setting the monochrome mode. Namely, a transfer belt 25 comes into contact with the photosensitive drum 24 first, and then the photosensitive drums 21, 22 and 23. This pattern is repeated. The transfer belt 25 does not come into contact with the photosensitive drums 21, 22, 23 and 24 at a time.

An image forming apparatus includes an inkjet head, a first tank and a second tank, a first flow path, a second flow path, a third flow path, and a negative pressure control mechanism that controls negative pressure in the first tank and the second tank. The negative pressure control mechanism alternately switches a first phase in which the ink is delivered from the first tank to the second tank, and a second phase in which the ink is delivered from the second tank to the first tank. The inkjet head ejects the ink both in the first phase and in the second phase.

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.

An image forming apparatus includes a carriage mounted with a recording head of an ink-jet system, a carriage driving mechanism, and a sheet conveying mechanism that conveys a sheet in a predetermined direction. The carriage is moved in a direction orthogonal to the conveying direction of the sheet by the carriage driving mechanism. A sheet guide member is arranged in a position below the recording head and opposed to the recording head. A sheet passes over a guide section of this sheet guide member. A heater is provided in the sheet guide member. This heater heats the guide section.
