Abstract

PURPOSE:To supply toner which is charged electrostatically and sufficiently to a developing sleeve smoothly by arranging an agitating means which agitates a 2nd developer and putting the toner in the developer in a developing device so that the toner can move to a 1st developer. CONSTITUTION:The 2nd developer 25 which contains nonmagnetic carriers and toner is put under the developing sleeve 19 of a developing device so that the toner can move to the 1st developer on the developing sleeve 19. The agitator roller 26 is arranged so as to agitate and change the 2nd developer 25 electrostatically and uniformly by friction against the nonmagnetic carriers. Namely, the toner in the 2nd developer 25 is charged uniformly and electrostatically through the rotary agitation of the agitator roller 26 and the charged toner is moved electrically to the 1st developer 21 to supply toner which is consumed as the development is carried out. Consequently, the toner is charged electrostatically and uniformly and supplied smoothly to the 1st developer on the developing sleeve.
