Abstract

See full text

Provided is a housing that encloses: a first developer transport member that transports developer, which includes toner, laterally in a first direction; a second developer transport member that transports the developer in a second direction opposite to the first direction; a first communication passage configured to direct the developer transported by the first developer transport member to an upstream edge, along the second direction, of the second developer transport member; and a second communication passage configured to direct the developer transported by the second developer transport member to an upstream edge, along the first direction, of the first developer transport member. The second communication passage progressively reduces the amount of developer directed through the second communication passage to the upstream edge of the first developer transport member as an inclination angle of the housing increases so that the second communication passage is lower than the first communication passage.
