Abstract
A developing unit in an image forming device is disclosed in which developer peeled off from a developing roller can be reliably retrieved to an agitation transport member and avoid being directly drawn thereto. A developing unit has a drawing magnetic pole and a peel-off magnetic pole. A first agitation transport member is arranged below a developing roller and agitates and transports the developer in the axial direction simultaneously and supplies it to the developing roller. A guide member has a sloping surface guiding the developer torn off from the developing roller to the first agitation transport member. The magnetic pole is arranged between horizontal positions of the sloping surface, and the magnetic pole is arranged horizontally outward of the lower end of the sloping surface.
