A multicolor image forming apparatus having a plurality of unicolor imaging units each equipped with at least a developing device anchored to a unit frame and an image carrier drum anchored removably to the unit frame with a predetermined space kept to a roll of the developing device. The unicolor imaging units are installed removably in the apparatus body while being supported respectively by means of slide rails attached to frames of the apparatus body, and toner images produced individually by the unicolor imaging units are transferred onto a recording medium to form a multicolor image. In this apparatus, a shaft fitter for fitting therein a shaft of the image carrier drum in each of the unicolor imaging units and a pin fitter for fitting therein an engagement pin infixed to project from the unit frame are provided respectively in a rear frame of the apparatus body and a support side plate anchored removably to a predetermined position of a front frame of the apparatus body, in such a manner that a predetermined space is kept between the shaft fitter and the pin fitter.
