Abstract
A toner collecting unit includes a housing, an inlet, a first fan, a lower duct, a first filter, and an oscillation motor. The inlet is provided in the housing. Toner flows into the inlet together with an air flow. The first fan is arranged in the interior of the housing and is configured to suck the air flow flowing from the inlet and to exhaust the air outside the housing. The lower duct guides the air flow upward from below. The first filter is arranged in an upper part of the lower duct so that its approach surface, which the air flow enters, faces downward.
