摘要

The present invention discloses an image forming apparatus comprising an image forming unit attachable to the body of the image forming apparatus and having at least a developing device which has a toner receiving opening, a toner supply member attachable to the body of the image forming apparatus and having a toner supply opening opposed to the toner receiving opening at a predetermined position when the unit is attached to the body of the image forming apparatus for supplying toner to the developing device through the toner supply opening, a covering member for selectively covering the toner supply opening, a fixing member for fixing the unit to the body of the image forming apparatus, and a moving member disposed in the body of the image forming apparatus for moving the covering member so that the toner receiving opening is open when the unit is fixed to the body of the image forming apparatus by the fixing member. The apparatus also includes aspirator means for collecting spilled toner to reduce the likelihood that toner spilled from the developing device will be scattered about.
