ABSTRACT:
An image forming apparatus includes a horizontal carrying mechanism that collects a waste developer in the horizontal direction, relay carrying mechanisms that carry the waste developer collected by the horizontal carrying mechanism to a desired position, a vertical carrying mechanism that carries the waste developer, which is carried by the relay carrying mechanisms, in the vertical upward direction, and a relay carrying mechanism that feeds the waste developer carried by the vertical carrying mechanism into a storage case. A waste developer flow rate of a waste-developer carrying mechanism at a post stage is equal to or larger than a waste developer flow rate of a waste-developer carrying mechanism at a pre-stage thereof.
