Abstract

PURPOSE: To perform ear cutting of developer surely and efficiently with a simple construction by providing an overflow path aside from a developer feed path.
CONSTITUTION: A partition plate 11 is provided from the side of the first feed roller 5 to the side of a developing roller 7 so as to nearly vertically bisect the spacing in the developing vessel between the wall surface 12a of the developing vessel 12 and the first, second feed rollers 5, 6 to delineate a developer feed path 13 and an overflow path 14. As a result, the developer is supplied to the developing roller 7 through the developer feed path 13 by the first, second feed rollers 5, 6 and the excess portions are dropped into the bottom of the developer case 12 through the overflow path 14, toghether with the developer scraped off by a doctor 8, thus it will not stagnate in the lower part of the doctor 8. Hence, only a constant amount of the developer on the developing roller 7 is conveyed and ear-cutting is accomplished surely and efficiently by a scraper 10.
