  • Publication number: 20140169841
    Abstract: An image forming apparatus comprises: an imaging unit including imaging subunits that are arranged in a vertical direction, each of the imaging subunits forming a toner image of a different color; an intermediate transfer belt having a running surface that runs vertically along the imaging subunits, and on which the toner images are primary-transferred and superposed; a secondary transfer unit secondary-transferring the toner images on the intermediate transfer belt to the recording sheet; and an ejection unit having an outlet and a conveyance path extending vertically, the ejection unit conveying, to the outlet via the conveyance path, the recording sheet on which the toner images have been secondary-transferred, wherein when viewed from a front of the image forming apparatus, the imaging unit is arranged behind the intermediate transfer belt, and the conveyance path is arranged in front of the intermediate transfer belt.
