Mechanism for effecting pressure engagement between two roll fuser members used for fusing toner images to copy substrates. The mechanism is characterized by simplicity of design and serviceability. To this end, one of two roll fuser members is supported on bearing surfaces such that it is lifted or raised upwardly through engagement with the other fuser member as it is moved upwardly. Upward movement of the last mentioned roll is effected by a pair of lever arms which serve as the support for that roll. Each lever arm is operatively attached to an over-center toggle structure which is actuatable either by rotary or linear motion of an actuator mechanism.
