A rotatable magnet roller is arranged inside the cylindrical sleeve and which is provided magnet poles facing the photosensitive layer. A movable scraper is pivotally supported and has a free end. The free end of the scraper allows passage of the developer which is conveyed on a surface of the cylindrical sleeve upon rotation of the magnet roller through a gap between the free end and the cylindrical sleeve when the free end is separated from the cylindrical sleeve by pivoting of the scraper. The free end scrapes off the developer when the free end contacts with the cylindrical sleeve.
