摘要： A developing device includes a first developing member that rotates in a manner such that a moving direction of a portion opposing the image carrier is opposite a moving direction of the image carrier, a second developing member provided on a downstream side of the first developing member in a rotating direction of the image carrier and rotates in a manner such that a moving direction of a portion opposing the image carrier is the same as the moving direction of the image carrier, a distributing member supported movably relative to a proximal portion where the first developing member is closest to the second developing member so as to distribute developer to the first and second developing members by contact with the developer, and an a biasing member that biases the distributing member upstream in the rotating direction of the first developing member.

摘要： A transporting member includes multiple helical blades that helically extend around a rotation shaft and that have an upstream-side blade and a downstream-side blade, an end portion of the upstream-side blade and an end portion of the downstream-side blade overlapping in a direction perpendicular to an axial direction of the rotation shaft, the multiple helical blades transporting an object in the axial direction via rotation of the rotation shaft; a gap portion that divides the upstream-side blade and the downstream-side blade, the upstream-side blade and the downstream-side blade being arranged at a certain angular interval in a circumferential direction of the rotation shaft; and a regulating portion that regulates an amount of the object that passes through a space between the upstream-side blade and the downstream-side blade in a direction in which the object is transported.

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.
摘要翻译：显影装置包括套筒和具有第一和第二磁极的磁性辊，第二磁极设置在第一磁极的下游。在从第一磁极到第二磁极的区域中的套筒上的磁吸引分布使得磁吸引力从第一磁极朝向下游侧的位置减小，磁吸引力的变化梯度减小在磁吸引减少梯度临时增加的区域下游的区域，从而形成磁吸引力减小的吸引减小区域，使得显影剂不能保持在套筒上，并且磁性变化的梯度吸引力降低区域下游的区域的吸引力增加，使得磁吸引力增加到第二磁极的位置。
