ABSTRACT:
A developer supply device provided is in contact with a developer carrying device. It comprises a surface member having at least one opening elongated in an axial direction of the developer supply device. The number of cellular walls counted in the circumferential direction is increased without increasing the number of openings so that the power of scraping the developer is increased. As a result, the dirty background on the print is minimized, thus enhancing the image quality.
