Abstract
PURPOSE:To rotate supply rollers independently and to supply toner uniformly by desposing divided supply rollers lengthwise in accordance with the copy width and by equipping the said rollers with a rotary clutch. CONSTITUTION:A supply roller 9 is divided lengthwise into a main roller 9a as a center part which has relatively large width and auxiliary rollers 9b as side parts. The both left and right auxiliary rollers 9b are stuck to a tube shaft 12 equipped to a shaft 8 through a unidirectionally rotary clutch 13. Then, the auxiliary rollers 9b rotate together with the shaft 8 according to the meshing direction of the clutch 13 or rotate independently without reference to the rotation of the shaft 8. Thus, each supply roller rotates independently according to the width of a copying form, and the variation of the amount of toner in the width direction of a developing device is prevented.
