Abstract:
A developing device includes a rotating member that delivers developer to a latent image on an image carrier while rotating; a supplying member provided in a supply path extending in an axial direction of the rotating member; a stirring member including a stirring shaft extending in the axial direction and provided in a stirring path extending in the axial direction and arranged side by side with the supply path in a direction intersecting the axial direction, the stirring member stirring the developer while rotating by causing the developer to circulate between the supply path and the stirring path; and a preliminary member provided in a preliminary stirring path into which toner is supplied from an outside and provided by extending an end of the stirring path that is on a side where the developer delivered from the supply member is received by the stirring member, the preliminary member including an extension shaft as an extension of the stirring shaft and a helical transporting blade provided on the extension shaft, the transporting blade being divided into a first transporting blade and a second transporting blade provided across the first transporting blade from the stirring shaft, the preliminary member transporting the toner into the stirring path while rotating.

Claim (Index 8):
The developing device according to  claim 1 ,\n wherein the supplying member includes a supplying shaft extending in the axial direction and a helical supplying blade provided on the supplying shaft, wherein the stirring member includes the stirring shaft and a helical stirring blade provided on the stirring shaft, wherein the developing device includes a partition member that separates the supply path and the stirring path from each other, the partition member being provided between a pair of openings through which the developer is delivered from the supplying member to the stirring member and from the stirring member to the supplying member, respectively, wherein the supplying shaft is provided with a reversal blade that is helical in a direction opposite to a direction in which the supplying blade is helical, the reversal blade being aligned with the supplying blade in the axial direction, and wherein the stirring blade and the first transporting blade are spaced apart from each other on a side nearer to the supplying blade with respect to the reversal blade in the axial direction and in an area facing one of the openings in a direction intersecting the axial direction.
