    摘要: An image forming apparatus having a pressing unit for pressing a fixing unit so that the fixing unit is secured to the apparatus body by the pressing force of the pressing unit. A projection portion on the fixing unit and an insertion slit in the apparatus body also secure the fixing unit, and thus, screws for securing the fixing unit to the apparatus body can be omitted and the fixing unit can easily be attached/detached. A discharge cover is rotatably mounted to the apparatus body and the fixing unit is inserted through an opening portion created when the discharge cover is opened.
