摘要： An image forming apparatus includes a latent image carrier and a developing device configured to develop a latent image carried by the latent image carrier. In the developing device, a receive-convey screw conveys a developer received from a developer carrier. The receive-convey screw includes a receive-convey blade including a lower, outer circumferential end located in a downstream end of the receive-convey blade in the developer conveyance direction of the receive-convey screw. A slant-convey screw is disposed obliquely relative to an axial direction of the receive-convey screw, and conveys the developer received from the receive-convey screw upward. The slant-convey screw includes a slant-convey blade including a lower, outer circumferential end located in an upstream end of the slant-convey blade in the developer conveyance direction of the slant-convey screw, the lower, outer circumferential end being located at a height level lower than the lower, outer circumferential end of the receive-convey blade.

摘要： A developing device is disclosed. The developing device includes a developing roller disposed to face an image carrier and a toner carrier capturing roller disposed to face the developing roller for capturing toner carriers adhered onto the image carrier. The developing roller generates a magnetic pole at a side facing the toner carrier capturing roller. A first virtual line, which connects a rotational center of the developing roller to a rotational center of the toner carrier capturing roller, passes through a region between a position where a magnetic flux density of the magnetic pole in the normal line direction is minimum on the developing roller at the upstream side in the rotational direction of the developing roller and a position where the magnetic flux density of the magnetic pole in the normal line direction is maximum on the developing roller.
