Abstract: A heater has a main heater block arranged in a reference area corresponding to a sheet having a reference size and a sub-heater block arranged in an outer-side area. An outer-side sheet sensor detects the sheet at a location within the outer-side area between a transfer device and a fixing device. The control device, depending on target size information representing a size of a target sheet, controls a power supply state between a first power supply state and a second power supply state. The control device, in a case in which the target size information represents a size exceeding the reference size, and depending on whether or not the outer-side sheet sensor detects the target sheet, further controls a conveying interval between the target sheet and a next sheet following the target sheet to one of a first interval and a second interval longer than the first interval.

Abstract: The fixing device includes a charge elimination member, a retaining member, a contact sheet metal, and a first contact member. The charge elimination member performs charge elimination from a recording medium by making contact with the recording medium that has passed through a fixing-and-nipping part. The retaining member has the charge elimination member fixed thereto. The contact sheet metal is held at a specified potential. The first contact member electrically connects the charge elimination member and the contact sheet metal to each other. The retaining member has a hollow cylindrical-shaped positioning boss, and the fixing housing has an insertion hole into which the positioning boss is to be inserted. The first contact member is placed inside the positioning boss and has one end protruded from the positioning boss. The contact sheet metal is placed so as to face the positioning boss.

Abstract: A fixing device includes a fixing member, a pressuring member and a temperature sensing part. The fixing member heated by a heat source contacts with a recording medium to heat a toner image on the recording medium. The pressuring member pressures the recording medium to the fixing member. The temperature sensing part in non-contact with the fixing member includes an infrared sensing element sensing infrared rays from the fixing member and a condensing member condensing the infrared rays to the infrared sensing element. Detection temperature of the fixing member is calculated with a sensing value by the infrared sensing element. The detection temperature or control temperature of the heat source is corrected with temperature deference between the infrared sensing element and the condensing member. Heating of the fixing member is controlled with the corrected detection temperature and the control temperature or the detection temperature and the corrected control temperature.
