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 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 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 first developing member rotating 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 is provided on a downstream side of the first developing member in a rotating direction of the image carrier rotating such that a moving direction of a portion opposing the image carrier is the same as the moving direction of the image carries. A distributing member is 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 a biasing member biases the distributing member upstream in the rotating direction of the first developing member.
摘要翻译：显影装置包括旋转的第一显影构件，使得与图像载体相对的部分的移动方向与图像载体的移动方向相反。第二显影部件沿图像载体旋转的方向设置在第一显影部件的下游侧，使得与图像载体相对的部分的移动方向与图像的移动方向相同。分配构件相对于第一显影构件最靠近第二显影构件的近侧部分可移动地支撑，以通过与显影剂接触而将显影剂分配到第一和第二显影构件，偏置构件将分配构件向上偏置在第一显影元件的旋转方向上。
