Abstract: A fixing device includes a first fixing member, a second fixing member, a pressing member, and a heating device. The first fixing member is in an ungrounded state and comes into contact with a toner image on a sheet. The second fixing member is arranged opposite the first fixing member. The pressing member presses the first fixing member against the second fixing member so as to form, at the contact portion between the first fixing member and the second fixing member, a nip portion through which the sheet passes. The heating device heats the first fixing member.

Abstract: A duration measuring section measures a plurality of times. A temperature measuring section measures a temperature of a heater at each of the times. A temperature information outputting section outputs heater temperature information. A temperature tendency computing section outputs temperature tendency information of the heater. A drive controller outputs linear velocity information for controlling the linear velocity of a pressure roller. A pressure roller drive section drives the pressure roller.

Abstract: A heater includes electrodes and heating element pieces. The electrodes energize the heating element pieces with electricity. The heating element pieces are connected to the electrodes and arranged through a gap portion in the heater in a main scanning direction. A ratio of a second surface area of the gap portion to a first surface area of the heating element pieces is 0

Abstract: A fixing belt heats and fixes a toner image. A pressure roller rotates the fixing belt while in contact with the fixing belt. A heater heats the fixing belt. A lubricating oil forms an oil film between the heater and an inner peripheral surface of the fixing belt. A pressure roller driver rotates the pressure roller so that the lubricating oil causes the fixing belt to be out of contact with the heater.
