Abstract
A developing device includes a developing roller, a toner supply roller, a regulating blade, a casing, a toner-reception supporting member, a toner reception member, and a vibration generating unit. The toner-reception supporting member is opposed to the developing roller or the toner supply roller between the regulating blade and the image carrier. The toner reception member is located so as to make a downward slope toward the toner supply roller side from the image carrier side along a longitudinal direction of the toner-reception supporting member. The toner reception member has a toner receiving surface that receives the toner dropping from the developing roller. The vibration generating unit vibrates the toner reception member. The toner reception member includes a sheet-shaped toner crushing member attached to overlap approximately a whole region of the toner receiving surface in a longitudinal direction. The toner crushing member is swingably supported with respect to the toner receiving surface.
