Abstract: An imaging system includes a rotatable image carrier; a rotatable developer carrier, a storage container, and an air flow generator. The developer carrier transfers toner to the image carrier at a developing region located between the image carrier and the developer carrier. The storage container stores the developer carrier. The air flow generator is separated from the storage container by a gap, and rotates in a rotational direction that is opposite to a rotational direction of the developer carrier, to channel an air flow through the gap when the air flow generator rotates.

Abstract: An imaging system includes a developing roller connected to a supply channel to supply a developing agent and to transfer toner in the developing agent to a photosensitive drum at a supply position, a regulation member located adjacent to the developing roller at an upstream side of the supply position to restrict a thickness of the developing agent; and a casing that forms a release chamber in the periphery of the developing roller between an upstream side of the regulation member and a downstream side of the supply position. The release chamber includes an outlet to discharge scattered toner to an inlet of the supply channel.

Abstract: A thermal printer includes a platen roller having both ends supported by a frame, a line thermal head having a plurality of heater elements and coming into contact with and separating from the platen roller, and a head mount supporting the line thermal head. The line thermal head has a heat sink mounted thereto for dissipating heat generated from the heater elements during printing on a recording sheet. The heat sink includes a first heat sink portion supported by the line thermal head through the head mount and a second heat sink portion which is connected to the first heat sink portion with a connector and which is removable.
