Abstract

PURPOSE: To reduce deterioration of image quality in successive recording, by incorporating a specified iron powder carrier with toner.
CONSTITUTION: With 100 wt. pts. of iron powder carrier having spherical form and a mean particle diameter of 50 to 250 μm, preferably, 70 to 150 μm and a surface oxygen amount of 0.3 to 0.75 wt. %, preferably 0.35 to 0.65 wt. % corresponding to surface oxidation, 0.5 to 7 wt. pts., preferably 1 to 5 wt. pts. of toner is blended. Magnetic brush control width c corresponding to the difference between gap a between recording drum 1 and developing roller 2 and gap b between roller 2 and developer control plate 3 is set to 0.4 to 2.2. mm, preferably 0.6 to 1 mm to perform development by the magnetic brush method.
