Abstract
An electrophotographic single-component developing device including a development roller; a toner storing portion provided in parallel relationship to an axis of the development roller, for storing a single-component toner; and a toner feeding unit provided in the toner storing portion, for feeding the single-component toner stored in the toner storing portion in a direction parallel to the axis of the development roller and supplying the single-component toner to the development roller. The toner feeding unit has a spiral agitator formed from a wire. Accordingly, the ability of toner feed along the development roller and the ability of toner supply to the development roller can be improved without deterioration of the toner.
