摘要： The present invention relates to an image forming apparatus so composed that it can be furnished with a plurality of developers (10, 11, 12, 13), can change the developer opposed to the photosensitive body (7) by integrally moving the corresponding developers (10, 11, 12, 13) and can compensate the position of the corresponding developer at the compensating position thereof on the way of an appointed movement and particularly relates to a system by which the positioning accuracy of the developers can be heightened without any waste time, thereby causing a high quality image to be formed. For this reason, the present invention features that the developers (10, 11, 12, 13) can be moved by a motor which can position, the position of the developers can be compensated only in the case that the appointed compensating position is on the most short-cut moving path when changing one of the developers to another developer, and the developers are changed through the most short-cut moving path.

摘要： A multicolor developing device having a plurality of developing mechanisms (136) for executing developing actions of colors different from each other. The developing device comprises a stationary frame member (2), a movable frame member (4) mounted on the stationary frame member to reciprocally move in a predetermined direction, and moving means for reciprocally moving the movable frame member. The plurality of developing mechanisms (136) are mounted on the movable frame member spaced apart in said predetermined direction, and any one of the plurality of developing mechanisms is selectively positionable at a developing zone depending on the movement of the movable frame member. The moving means includes a screw means (80) having a threaded shaft (82) extending in said predetermined direction and a nut (84) engaged with the threaded shaft, a stepping motor (114) for rotating the threaded shaft, and a nonexcited operation-type electromagnetic brake (134). A pair of racks (40) are disposed on the stationary frame member so as to be spaced apart in the lateral direction, and the movable frame member is provided with a rotary shaft extending in the lateral direction and a pair of pinions (74) fitted to the rotary shaft, the pair of pinions being engaged with the pair of racks. Each of the developing mechanisms (136) is provided with a pair of distance-setting rollers (156) which are brought into resilient contact with a rotary drum (160) in order to accomplish the positioning of the developing mechanisms relative to the rotary drum.

摘要： A housing accommodating a fur brush and a cleaning blade is pivoted to a position close to a photoconductive drum or at another position far from the photoconductive drum by positioning a positioning shaft. When the positioning shaft is slid for moving the positioning shaft away from a photoconductive drum, an operating member attached to the positioning shaft is put into contact with a pivoting lever to raise the pivoting lever away from the photoconductive drum. Since the pivoting lever is attached to a blade shaft, a cleaning blade attached to the blade shaft is pivoted away from the photoconductive drum.

摘要： A movable frame is mounted on a stationary frame so as to be reciprocatingly moved in a predetermined direction by a moving means. The movable frame is equipped with a plurality of developing mechanisms which may be selectively located at a developing position by the motion of the movable frame to carry out multi-color developing. The developing mechanisms are urged toward a rotary drum. In order to prevent the developing agent from scattering, side sealing pieces are provided near the non-developing operation region on both sides of a sleeve member in a magnetic brush mechanism of each developing mechanism. A toner container unit including toner containers and toner feeding means is rotatably supported by the stationary frame. The toner feeding means includes a extensible and contractible means which is detachably coupled to the developing mechanism. The toner container unit is selectively brought to a predetermined fixed position relative to the developing mechanism and to a predetermined retracted position turned in a direction to separate away from the developing mechanism.
