An image forming apparatus includes: a fixing device having a nip portion in which a recording material having an unfixed image is nipped and conveyed and the unfixed image is fixed to the recording material; a pressure applying device for applying a pressure to the nip portion; a pressure release device for releasing the pressure in the nip portion; and a detection device for detecting a presence or absence of the recording material. When the pressure in the nip portion is released by the pressure release device, the detection device outputs a detection result representing the presence of the recording material. The pressure release device have a plurality of levers for releasing the pressure and the levers are arranged at both ends of the fixing device in a direction perpendicular to a moving direction of the recording material.
