Abstract: Provided is a fixing device including a fixing member that fixes toner onto a recording material, a pressurizing member that forms a nip portion, through which the recording material passes, between the fixing member and the pressurizing member, a moving member that is disposed to be movable in response to passage of the recording material in a transport path of the recording material which passes through the nip portion, a detection unit that detects a presence or absence of the moving member, a displacement mechanism that changes a position of the pressurizing member with respect to the fixing member, and an attachment/detachment member that is disposed in a detachable manner at a facing position facing the displacement mechanism and comes into contact with the moving member.

Abstract: Provided is a fixing device including a fixing member that fixes toner to a recording material, a pressurizing member that forms a nip portion through which the recording material passes between the fixing member and the pressurizing member, a contacting and separating mechanism that contacts and separates the pressurizing member with and from the fixing member, and a pressure adjusting mechanism that is provided capable of advancing to and retreating from a region that moves along with contacting and separating of the pressurizing member with and from the fixing member by the contacting and separating mechanism while moving along a straight line direction, and adjusts a pressure in the nip portion by contacting the contacting and separating mechanism in the region.
