Abstract
A toner collection device including a toner container for collecting therein toner is provided. The present device includes a toner container provided with an inlet opening through which toner is collected, a container holder generally in the shape of a tray for holding thereon said container and means for moving said holder and container in a predetermined fashion. That is, in accordance with the present invention, the container is subjected to a periodic rocking motion such that it moves at an accelerated speed when directed in a predetermined direction and it moves at a slower speed in its returning motion. Thus, when the container is suddenly halted at the end of the going stroke, a heap of toner formed inside the container collapses to make room for further incoming toner. As a result, the packing density of the toner into the container is always insured to be above a predetermined level.
