Abstract

PURPOSE:To prevent uneven development or undevelopment to obtain the picture having excellent quality by providing a mesh grid to the boundary part between a toner vessel and a developing vessel and oscillating the grid. CONSTITUTION:A mesh grid 10 having a finer mesh than the solid of toner is provided close to the boundary part 100 between a developing vessel 2 and toner hopper 3 so as to rotate around a supporting axis 10 as a fulcrum and oscillated vertically through cam 12 and lever 13. Although normal toner in the hopper 3 passes through the grid 10 on the basis of the constitution, solid toner or foreign matters is catched by the grid 10 and then the solid toner is granurated by the oscillation of the grid 10 and fed to the developing vessel 2. Thus, uneven development or undevelopment caused by solid toner can be prevented and the picture having excellent quality is obtained.
