Abstract: A transfer unit includes a belt member, a bending roller, a transfer section, and a bias application unit. The belt member is extended between rollers and has a movable surface on which a toner image is transferred from an image carrier. The bending roller externally contacts the surface of the belt member to bend the belt member and rotates in conjunction with the belt member. The transfer section includes one of the rollers and a surface moving member. The surface moving member rotates at least one full turn while cleaning is performed on the surface moving member and the bending roller. A surface moving speed of the bending roller is equal to or greater than a surface moving speed of the surface moving member. A circumferential length L1 of the surface moving member and a circumferential length L2 of the bending roller satisfy L1≧L2.

Abstract: A cleaning apparatus is for removing a toner from a surface of an endless belt. The cleaning apparatus includes a blade, a blade holding structure, and an abutment maintaining structure. The blade abuts on the endless belt that is supported on a tension roller. The blade holding structure holds the blade with its rotation restricted, in a movable manner in the direction of motion adjustment to adjust tension on the endless belt, and causes the blade to abut on a winding area of the endless belt with respect to the tension roller. The abutment maintaining structure allows the blade to follow up movement of the tension roller to thereby maintain abutment of the blade on the endless belt.

Abstract: A belt member faces a plurality of carrying bodies that respectively carry toner images or developers. A plurality of facing members respectively faces the carrying bodies via the belt member. A detaching unit brings at least one of the facing members to face a corresponding carrying body and detaches other facing members from other carrying bodies. A contacting member contacts the belt member to detach the belt member from the other carrying bodies when the detaching unit detaches the other facing members from the other carrying bodies.

Abstract: A fixing device includes a fixing belt, a first heater, a second heater, a supporting roller, and a counter roller. During activation of the fixing device, a maximum power is supplied to the first heater, and only the first heater heats the fixing belt. When a temperature on the fixing belt reaches a first reference temperature, the fixing belt is driven rotationally, the power supplied to the first heater is dropped, and power is supplied also to the second heater. When the temperature on the fixing belt reaches a target temperature and the temperature on the counter roller reaches a second reference temperature, fixing operation is allowed to start.
