Abstract
A fixing device includes a roller arranged to come into contact with a recording member bearing an unfixed image thereon so as to fix the unfixed image to the recording member, and a separation member arranged to come into contact with the roller so as to separate the recording member from the roller. A fore end of the separation member on a side for coming into contact with the roller is formed in a curved surface and intrudes into the roller. An amount of intrusion of the separation member into a surface of the roller is not less than a radius of a circle of curvature of the curved surface of the fore end of the separation member and not more than a diameter of the circle of curvature.
