Abstract
An image forming apparatus includes plural image holders that hold an image; plural development devices that produce an image on the plural image holders; an intermediate transfer body supported by plural support members; plural first transfer devices that transfer images that are present on the plural image holders to the intermediate transfer body; a second transfer device that transfers a composite image from the intermediate transfer body onto a recording medium; a fixing device that fixes the composite image onto the recording medium; an ejection device that ejects the recording medium having the composite image transferred thereto out of the image forming apparatus main body; and a recording medium stacking part where ejected recording media are stacked.
Claims20
An image forming apparatus comprising:
- a plurality of image holders that hold an image respectively;
- a plurality of development devices that produce an image on the plurality of image holders respectively;
- an intermediate transfer body supported by a plurality of support members;
