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： A fixing device includes an endless belt rotatable in a predetermined direction of rotation and a nip formation assembly disposed opposite an inner circumferential surface of the endless belt. An opposed rotary body is pressed against the nip formation assembly via the endless belt to form a fixing nip between the endless belt and the opposed rotary body through which a recording medium bearing a toner image is conveyed. A belt holder contacts and supports each lateral end of the endless belt in an axial direction thereof. The belt holder is isolated from the opposed rotary body with a first interval interposed therebetween in the axial direction of the endless belt.

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.
