Abstract:
A developing device includes a developer container configured to accommodate a developer containing toner and a carrier; and a feeding screw provided rotatably in the developer container and configured to feed the developer in a predetermined feeding direction, the feeding screw including a rotation shaft, and a first helical blade and a second helical blade which are formed around the rotation shaft and which form a multi-thread helical blade. The feeding screw includes a region in which a plate-like projection portion is provided on the rotation shaft between the first helical blade and the second helical blade. The plate-like projection portion is provided so as to contact an adjacent helical blade on a downstream side with respect to the feeding direction without contacting an adjacent helical blade on an upstream side with respect to the feeding direction.

Claim (Index 7):
A developing device according to  claim 1 , wherein said feeding screw includes a first region in which a first plate-like projection portion which does not contact the helical blade on the upstream side with respect to the feeding direction and which contacts the helical blade on the downstream side with respect to the feeding direction and a second region, adjacent to said first region with respect to the feeding direction, in which a second plate-like projection portion which does not contact the helical blade on the upstream with respect to the feeding direction and which contacts the helical blade on the downstream side with respect to the feeding direction, and\n wherein a shape of said first plate-like projection portion is different from a shape of said second plate-like projection portion.
