Abstract
PURPOSE: To make developer conveying accurate and sure and obtain the developed images of high densities and good reproducibility by forming developer pools in the inlet region of the developing part and maintaining developer amount, shape and particle density always stable.
CONSTITUTION: The knife edge parts of plates 12, 13 form developer pools T", T' in the inlet region of the developing part, by which the respective developer amounts and shapes of the pools are maintained always constant. When a magnet roll 11 is rotated, the developer coming out from a vessel 10 and having been defined by the plate 12 subsequently moves on the peripheral surface of a cylinder 9, thereby subsequently forming and growing the pool T' and immediately maintaining the same constant. Namely, the growth ceases and the toner amounts and the inclination of the surfaces are maintained constant, whereby the particle densities are maintained stable. Then, even if the patterns of the electrostatic images change, the developed images which are visualized faithfully down to fine images having always even and high density and constant reproducibility may be obtained.
