An image forming apparatus includes individually replaceable image forming assemblies forming images of different colors; a storage portion that stores time when at least one image forming assembly currently loaded into the apparatus is unloaded; a calculating portion that calculates an unloaded-engine storage period, time elapsed from when a newly loaded image forming assembly is unloaded last time to when the image forming assembly is newly loaded; and a controller that performs image quality adjustment depending on the unloaded-engine storage period calculated before the newly loaded image forming assembly is used for image formation. The apparatus receives image data of an image that contains a color other than colors that currently loaded image forming assemblies form. The apparatus forms a final image based on the image data on a sheet through image forming operations on the same sheet while at least one of the loaded image forming assemblies is replaced.
