Abstract

PURPOSE:To reduce the cost of the whole device by providing a control member for controlling in advance a developer scraped by a developer scraping end, on the opposite side in the rotational direction of a developing roller from the developer scraping end. CONSTITUTION:A control member C for controlling in advance a developer 2 scraped by a developer scraping end 24a is provided on the opposite side Bl in the rotational direction of a developing roller 22 from the developer scraping end 24a. Accordingly, 2 which adheres to the spike rise forming plate 24, a resistance value of the developer 2 is varied by the image adjusting means. In such a way, a delicate adjustment of the image can be executed easily.
