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 developer-agitating transporter includes helical blades that helically extend around a rotation shaft, the helical blades being arranged at different positions in a direction perpendicular to a longitudinal direction of the rotation shaft; and a gap portion that divides each helical blade into a first blade portion and a second blade portion, which oppose each other across the gap portion, so that the helical blade is discontinuous in a direction in which the helical blade extends. The gap portion causes the first blade portion and the second blade portion to be arranged at a certain angular interval in a circumferential direction of the rotation shaft, and at least one surface of adjacent ones of the helical blades that are adjacent in the circumferential direction of the rotation shaft has a sloped area that is sloped at an angle that changes with respect to an axial direction of the rotation shaft.

摘要： A container for developer detachably mountable to an image forming apparatus body includes a container body, a discharge member, a resistive member, and a resistance reduction mechanism. The container body contains developer and is rotated when drive is transmitted from the image forming apparatus body. The discharge member supports the container body rotatable relative to the discharge member and has a discharge port through which the developer is discharged. The resistive member is brought into contact with the container body so as to apply resistance to the rotation of the container body. The resistance reduction mechanism changes a contact state between the resistive member and the container body so as to reduce the resistance between the resistive member and the container body when the container is mounted to the image forming apparatus body.

摘要： A developing device includes a sleeve and a magnet roller having first and second magnetic poles, the second magnetic pole being disposed downstream of the first magnetic pole. A magnetic attraction distribution on the sleeve in a region from the first magnetic pole to the second magnetic pole is such that the magnetic attraction decreases from a position of the first magnetic pole toward the downstream side, a gradient of change in the magnetic attraction decreases in a region downstream of a region in which a gradient of reduction in the magnetic attraction temporarily increases, thereby forming an attraction reduction region in which the magnetic attraction is reduced so that developer cannot be held on the sleeve, and the gradient of change in the magnetic attraction increases in a region downstream of the attraction reduction region so that the magnetic attraction increases to a position of the second magnetic pole.
