摘要： A fixing device includes a controller connected to a heater and at least one of a pressing rotary body and an endless rotary body. The controller performs a first fixing operation, a first transition operation, a second fixing operation, and a second transition operation. The first fixing operation fixes a toner image on a first recording medium after the fixing device is powered on. The first transition operation rotates the pressing rotary body and the endless rotary body while controlling the heater to maintain the endless rotary body at a predetermined temperature for a first duration time. The second fixing operation fixes a toner image on a second recording medium. The second transition operation rotates the pressing rotary body and the endless rotary body while controlling the heater to maintain the endless rotary body at the predetermined temperature for a second duration time smaller than the first duration time.

摘要： A fixing device for fixing an unfixed image onto a recording medium includes a fixing belt, a nip forming member, an opposing rotary member, a heater, and a temperature detector. The fixing belt is formed into a loop to move endlessly and fix the unfixed image on the recording medium. The nip forming member is disposed inside the loop formed by the fixing belt. The opposing rotary member contacts the nip forming member via the fixing belt to form a nip portion therebetween while rotating. The heater heats the fixing belt at a place other than the nip portion. The temperature detector detects a temperature of the surface of the fixing belt. The temperature detector detects the temperature near a place of the fixing belt that easily deforms as the fixing belt is heated by the heater.

摘要： The fixing device includes a nip formation assembly partially pressing against an opposed rotary body via an endless belt to form a fixing nip between the endless belt and the opposed rotary body. The nip formation assembly includes a base pad defining the fixing nip and including a pressure portion, an extension portion, and a curved portion. The pressure portion presses against the opposed rotary body via the endless belt. The extension portion is contiguous to and disposed upstream from the pressure portion in a recording medium conveyance direction. The extension portion does not press against the opposed rotary body via the endless belt. The curved portion is disposed upstream from the extension portion in the recording medium conveyance direction and smoothly blends into the extension portion. The curved portion does not press against the opposed rotary body.
