Abstract
In a fixing device of an image forming apparatus, a pressure lever includes an engagement recess for holding a pressure release lever at a pressure position where a biasing member is actuated, and the pressure release lever includes an engaging protrusion which can be engaged with the engagement recess. Also, the pressure lever includes a slidable contact portion adjacent to the engagement recess. The pressure releaser is capable of increasing or decreasing biasing intensity of the biasing member as the engagement protrusion is slid along the slidable contact portion by a biasing force of the biasing member between a state in which the pressure releaser is at the pressure position and a state in which the pressure releaser is at a release position for releasing pressure contact.
