Abstract
A fixing device includes a first rotary member, a second rotary member, a support member having a connection part, an urging member, and an engaging member. The engaging member is capable of changing a state of the fixing device between a pressure applied state and a pressure reduced state using the urging member and the support member. When the nip pressure is in the pressure applied state, the engaging member changes a position of the urging member to direct the urging member longitudinally in a tangential direction to an arc that has a center coinciding with a center of rotation of the support member and that passes through the connecting portion. When the nip pressure is in the pressure reduced state, the engaging member changes the position of the urging member to direct the urging member longitudinally in a direction different from the tangential direction.
