Claims

[Scope of utility model registration request]

a fixed roller rotatably mounted on a support;
In a pressure roller pair of a pressure fixing device or the like, which includes a pressure roller that presses against the fixed roller, a support member that is provided on the support body and supports one end of the shaft of the pressure roller, and a support member that is displaceably attached to the support body. A lever is provided to support the other end of the shaft of the pressure roller, and a rotatable cam that displaces the lever. A contact/separation mechanism for a pair of pressure rollers, characterized in that the pressure roller is brought into contact with and separated from the fixed roller by moving only the other end toward or away from the fixed roller.
