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.

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 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 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.

摘要： A developing device includes a developer-carrying member and a developer control member, a supply member, and a rotating member that are disposed opposite the developer-carrying member. The developer-carrying member accommodates a magnetic source that generates a magnetic force for carrying a developer containing magnetic particles on an outer surface thereof. The developer control member controls the thickness of a layer of the developer carried on the outer surface of the developer-carrying member. The supply member rotates to transport the developer in a rotation axis direction thereof and to supply the developer to the developer-carrying member. The rotating member is disposed at a position where the rotating member is submerged in the developer between the developer control member and the supply member and rotates to supply the developer from between the developer control member and the supply member to the supply member.
