Abstract
PURPOSE: To obtain a one component developing apparatus for conveying a toner and impressing the electric charge exactly, by applying DC voltage between the magnetic brush and the developing roll provided closely adjacent to said brush.
CONSTITUTION: A magnetic brush 3 by the magnetic powder carrier which has mixed nonmagnetic toner particles 2''' is formed in the circumference of the magnet sleeve 3b. The DC voltage required is applied between the brush 3 and the developing roll 4 provided close to this brush 3, by DC power supply 6. As a result, the electric charge required is exactly impressed to the toner 2..., also that electric discharge is not caused by the magnetic powder carrier of high resistance in accordance with the electric field by the DC voltage, and therefore the melt sticking is prevented and the toner 2... is conveyed exactly. Accordingly, since the toner is fed stably to the developing roll, the developing treatment is executed by use of a satisfactory one component developing agent without deteriorating a picture quality.
