CHANNEL FOR RECIRCULATING AIR FLOW, ELECTROPHOTOGRAPHIC PRINTER USING SAME, AND CLEANING DEVICE THEREFOR

PROBLEM TO BE SOLVED: To provide a channel for recirculating an air flow adjacent to the marking particle flow substantially projecting in the tangent direction from the marking particle transporting member inside a developing device. SOLUTION: The marking particle flow prescribes the inside border 310 extending in the tangent direction from a first position 306 adjacent to the transporting member, and also prescribes the outside border 312 distant from the transporting member and the inside border 310. The channel 330 includes the first member 342 arranged outside the marking particle flow. At least a part of the first member 342 is substantially adjacent to the outside border 312 of the marking particle flow, however is arranged apart from the transporting member. The channel 330 includes also the second member 346 combined with the first member 342 and the third member 345 combined with the second member 346. The second member 346 is arrange adjacent to the transporting member, but apart from the marking particle flow. The entire air flow substantially decide in the direction by the first member 342, is successively directed by the second member 346 and the third member 345.
