Abstract

PURPOSE:To prevent a filter effect caused by toner stuck to an unexposed part and to form a distinct image without the occurrence of a black positive image memory by specifying the weight concentration of the toner in two- component developer. CONSTITUTION:An electrostatic latent image is developed to be formed into a developed image by a developing means 5 which uses the two-component developer D consisting of the toner (b) and a carrier (c) and then the developed image is transferred on paper P conveyed from a paper supply cassette 9 by using a transfer means 6. And the developed image is fixed on the paper P by a fixing device 15 so as to be ejected onto a paper ejecting tray 12. The weight concentration of the toner in the two-component developer, which is used in the developing means 5, is set less than 6wt.%. Then, the stirring of the developer is sufficiently executed and the occurrence of the toner of opposite polarity is prevented. Thus, the filter effect caused by the adhesion of the toner of the opposite polarity to the unexposed part can be prevented and the distinct image without the black positive image memory can be formed.
