An image forming apparatus includes an optical unit emitting light in accordance with image information that is inclined in a prescribed direction. At least two image bearing members bearing a latent image formed by the light emitted from the optical unit are provided that have shafts arranged on a line inclining in the prescribed direction. At least two developing units are provided for developing the at least two latent images with toner. Shafts of the at least two developing means units are also arranged on a line inclining in the prescribed direction. An intermediate transfer belt is provided to receive and superimpose the toner images from the at least two image bearing members at a first transfer station. The intermediate transfer belt also inclines in the prescribed direction. A transfer unit is connected to a cover of a main body and transfers the superimposed toner images from the intermediate transfer belt to a recording medium at a second transfer station. This transfer unit is arranged in a vicinity of the lower end of the intermediate transfer belt with the transfer unit being separated from the intermediate transfer belt when the cover is opened.
