DEVELOPING DEVICE AND COLOR ELECTRO-PHOTOGRAPHIC DEVICE

摘要

PROBLEM TO BE SOLVED: To stabilize the circulation of excessive toner by forming a thin layer of toner on a developing roll. SOLUTION: Excessive toner 9a resulting from the formation of a thin layer of toner on the surface of the developing roll 1 or toner 9a recovered from the developing roll is stirred by a rotary stirring member 4 in a recovery path 25 and, at the same time, it is pushed out into a toner storage chamber 6 to be circulated. The rotary stirring member 4 also acts so as to restrict the reverse flow of the toner 9 in the toner storage chamber 6 to the recovery path 25.
