Abstract:
1. An image forming apparatus, comprising: a casing including an ejection tray; a plurality of image carriers arranged in parallel along a first direction, each of the plurality of image carriers being configured to have an electrostatic latent image formed thereon and to rotate about an axis extending along a second direction perpendicular to the first direction; a plurality of developing agent carriers opposed to the plurality of image carriers, each of the plurality of developing agent carriers being configured to feed a developing agent to a corresponding one of the plurality of the image carriers; an intermediate transfer belt arranged above the plurality of image carriers and configured to come into contact with all the plurality of image carriers; a secondary transfer roller opposed to the intermediate transfer belt; a cleaning unit arranged above the intermediate transfer belt and configured to clean toner adhering to a surface of the intermediate transfer belt; an exposure unit arranged below the plurality of image carriers and configured to form the electrostatic latent image on each of the plurality of image carriers; and a plurality of developing agent cartridges configured to be arranged in parallel along the first direction, each of the plurality of developing agent cartridges being configured to be opposed to each of the plurality of the developing agent carriers, respectively; a fixing unit arranged above the second transfer roller; and a sheet ejection roller arranged between the fixing unit and the ejection tray; wherein the ejection tray is disposed above the intermediate transfer belt; wherein each of the plurality of developing agent cartridges is configured to be disposed overlapping a corresponding one of the plurality of image carriers, a corresponding one of the plurality of developing agent carriers, the intermediate transfer belt and the ejection tray in a third direction parallel to the second direction, and wherein one of the plurality of developing agent cartridges is configured to be disposed overlapping at least a part of the sheet ejection roller in the third direction.
