ABSTRACT:
An electrophotographic image forming apparatus prevents deformation of a pressing roller and to improves printing quality. The electrophotographic image forming apparatus includes a case and a developing unit removably installed in the case. The developing unit includes a housing and toner contained in the housing. A fixing unit fixes a toner image formed by transferring toner to paper received from the developing unit. The fixing unit includes a heating device that heats the paper on which the toner image is formed and a pressing roller that presses the toner image on the paper. A lever is pivotally fixed between the developing unit and the fixing unit. A first end portion of the lever supports the developing unit and a second end portion presses the pressing roller toward the heating device when the developing unit is installed in the case.
