Summary:PURPOSE:To prevent the accumulation of the large quantity of toner partially or fully in a space securely by forming a strut part dividing small hole formed on a scraper so as to form a proper angle with the relative displacing direction between a magnet roller and the scraper. CONSTITUTION:Many small holes 5a are arrayed close to the scraper edge 5c of the leading end of the scraper 5 and the strut parts 5b dividing respective small holes 5a are formed so as to make an angle of theta with the center axial line C of the magnet roller. The advancing direction of toner scraped off by the scraper edge 5c and accumulated in the space is made almost coincide with the direction intersecting with the center axial line C, i.e. the direction of an arrow B. When the toner reached the strut part between the adjacent small hole 5a is advanced in the arrow B direction by the toner successively supplied by the magnet roller, the toner is not advanced along the strut part 5b and reaches the small hole 5b and falled on the magnet roller side because the strut part 5b is expanded in a direction different from the arrow B direction.
