摘要： A fixing device includes two rotary bodies and a recording-medium separation unit. The two rotary bodies are pressed against each other to form a nipping portion. The recording-medium separation unit is disposed at a position downstream from the nipping portion in a direction in which the recording medium is conveyed. The recording-medium separation unit includes a separation plate holder, a separation plate, and a spring. The separation plate holder extends in a longitudinal direction of one of the rotary bodies to hold the separation plate away from the one of the rotary bodies. The separation plate holder has rotation fulcrums and positioning surfaces at both ends in the longitudinal direction. The positioning surfaces are urged by the spring toward the one of the rotary bodies. Each of the positioning surfaces has a bent side to form a flange surface having one of the rotation fulcrums.
