Abstract

A developer dispersing device which can be utilized for moving dry two-component toner is applicable to electro-photographic apparatuses such as copiers, printers or facsimile machines. The developer dispersing device includes a rotatable shaft on which pumping plate members and blades are positioned so as to both laterally and radially move toner. The pumping plate member and blades are positioned on the shaft to permit an efficient lateral and radial displacement of the toner in combination with positively mixing newly supplied toner with stock toner so as to provide for an even image density.
