摘要: A fixing device includes a fixing member formed into a loop and rotatable in a predetermined direction of rotation. A heating assembly faces a first region on an inner circumferential surface of the fixing member to heat the fixing member. The heating assembly is thermally deformed to contact and move the fixing member. A first fixing member support and a second fixing member support face a second region on the inner circumferential surface of the fixing member other than the first region. The first fixing member support and the second fixing member support contact and support the rotating fixing member moved by the thermally deformed heating assembly.

摘要: A fixing device includes an endless, fuser belt, a contact member, a pressure member, a heater, a first thermometer, a second thermometer, and a controller. The fuser belt is looped into a generally cylindrical configuration. The contact member extends inside the loop of endless belt. The pressure member extends with the belt interposed between the contact member and the pressure member. The pressure member is pressed against the contact member through the fuser belt to form a fixing nip. The heater includes a first heating element and a second heating element. The first heating element heats the fuser belt at a first position. The second heating element heats the fuser belt at a second position. The first thermometer detects a first temperature of the fuser belt. The second thermometer detects a second temperature of the fuser belt. The controller controls each of the first and second heating elements.

摘要: A fixing device includes a heat source; a fixing member looped into a generally cylindrical shape to rotate in a circumferential direction thereof and partially heated by the heat source and to heat a surface of a recording medium bearing an unfixed toner image to fix the unfixed toner image thereon in a fixing process; a rotary pressing member disposed facing the fixing member to form a nip therebetween, through which the recording medium is transported in a transport direction; and a rotation driver to rotate one of the fixing member and the pressing member. In a case in which the fixing member is halted for a reason other than the fixing process while power of the fixing device is on, electric power is not supplied to the heat source and the fixing member is rotated by a predetermined amount or more after the fixing member is halted.
