摘要： A developing device is provided. A rotating shaft of a first transporting member is positioned exactly below a developer carrier. A second virtual tangent to the first transporting member that extends vertically on a side of the first transporting member opposite an image carrier is farther from the image carrier than a first virtual tangent to the developer carrier that extends vertically on a side of the developer carrier opposite the image carrier. A distance between the two virtual tangents is shorter than a distance between the first virtual tangent and a developer container. A developer guiding member that guides a developer toward a downstream side in a direction of transport by the first transporting member is provided on a downstream side in a direction of rotation of the developer carrier with respect to the image carrier, with a gap provided with respect to the developer carrier.

摘要： A developing device includes a developer container; a developer carrier; a first transport member having a rotation shaft and a transport blade; a second transport member having a rotation shaft and a transport blade; a partition member; a guide member; a first inflow portion; a second inflow portion; and a movement portion. The rotation shaft of the first transport member is located within a projection area of the developer carrier projected from above. A second imaginary tangent line extending vertically and touching an outer end of the transport blade of the first transport member is farther from the image carrier than a first imaginary tangent line extending vertically and touching an outer surface of the developer carrier. A first distance between the first and second imaginary tangent lines is smaller than a second distance between a rotation center of the image carrier and an inner surface of the developer container.

摘要： A developing device includes a developing housing that contains developer; a developer carrier that transports the developer; a layer-thickness regulating member that is provided for an upstream gap between the developer carrier and the developing housing and that regulates a layer thickness of the developer; and a sealing member that is provided for a downstream gap between the developer carrier and the developing housing. The sealing member is fixed to the developing housing at one side and is in contact with the developer on the developer carrier at the other side. The sealing member has cuts extending from a free end of the sealing member by approximately 60% or more of a dimension of the sealing member from the free end to a fixed end in the width direction, and is at an angle of approximately 30° or less with respect to a reference line.
