<p>Provided is an image forming apparatus, which can be free from clogging in waste toner transfer passages and have a high accumulation performance in the waste toner recovering container, and can make effective use of the capacity of the waste toner recovering container, even if the structure of which is so constituted as to include a plurality of image forming units having photosensitive elements and to gather and transfer the toners removed from the individual photosensitive elements thereby to accumulate the toners in a waste toner recovering container,. The image forming apparatus comprises a plurality of image forming units having photosensitive elements, a plurality of toner containers, cleaning units for removing the toners left on the photosensitive elements, a waste toner recovering container for accumulating the waste toners removed from the photosensitive elements, and waste toner transfer passages connecting the cleaning units and the waste toner recovering container, for transferring the waste toners to the waste toner recovering container. The waste toner transfer passages, which is formed in the image forming unit using the toner container of the largest capacity, for transferring the waste toners in the cleaning units, is to be longest.</p> |
