Abstract

PURPOSE: To effectively mix the developer and toner with good efficiency only by the flow of the developer by so disposing plural scrapers in such a manner that they have a spacing in the circumferential direction and subsequently scrape off and remove the developer and providing a toner replenishing mechanism between the scrapers.
CONSTITUTION: The developer A which has not been used for developing is moved by the rotation of a developing roll 3 and is removed by the first scraper 5 and flows along this. At this time, the spacing t1 between the leading end 5a of the scraper 5 and the surface 3a of the roll 3 is wide and therefore a certain degree of the developer deposits and remains on the roll 3 and the other developer is craped off by the second scraper 6 and flows downward along this. When it arrives at the lower part of a toner replenishing mechanism 7, the toner B falls and deposits thereon. In addition, it flows along the scraper 5 and the developer having trespssed its end part 5b falls and deposite on the upper part of the toner B. The deposits composed of these 3 layers fall on the bottom of a developing devive box 6b from the end part 6b of the scraper 6. Thereby, the developer and toner and mixed with good efficiency only by the flow of the developer.
