    摘要: A color printer including a photoconductive belt, a black developing unit which is located adjacent the photoconductive belt and a revolving type developing unit which is located adjacent the photoconductive belt and has a developing position on the photoconductive belt which is different from that of the black developing unit. The revolving type developing unit has a yellow developing device, a magenta developing device and a cyan developing device, each including a detachable toner cartridge by which yellow toner, magenta toner and cyan toner is replenished. The black developing unit is replaceable independent of the revolving type developing unit by being removably mounted on a removable frame on which the revolving type developing unit is mounted. Both developing units are removable from the color printer as a body by removal of the removable frame from the color printer.

    摘要: Image forming equipment of the type having a revolver type or rotational developing device. The revolver type developing device is rotatable about a shaft to bring any one of a plurality of developing units to a developing position where the developing unit faces an image carrier for effecting development. A protective member rotatably accommodates the developing device therein and has an opening which faces the image carrier at the developing position when the protective member is mounted on the equipment. Rotation restricting means is provided for selectively inhibiting the developing device from rotating relative to the protective member.

    摘要: An image forming apparatus having an image carrier for electrostatically forming a latent image thereon, and a revolver type developing device located in close proximity to the image carrier and having a plurality of developing units each containing a powdery developer of particular color arranged around a rotary shaft, and rotating the developing device to selectively locate one of the developing units at a developing position where the developing unit faces the image carrier for developing the latent image. A guide member is mounted on a body of the apparatus and formed with an engaging portion for guiding the developing device toward and away from the image carrier in engagement with the rotary shaft. A movable member holds the developing device in such a manner as to allow it to be mounted and dismounted in the up-and-down direction and causes the device to move along the guide member.

    摘要: A rotary developing device incorporated in image forming equipment has a plurality of developing units rotatably mounted on a rotary shaft and rotating the developing units for sequentially developing latent images electrostatically formed on an image carrier at a developing position where the developing units sequentially face the image carrier. First side plates are formed integrally at least with the rotary shaft. Partitions extend radially away from said rotary shaft for separating said developing units from one another. Second side plates are respectively removably mounted on the first side plates. At least a developer carrier included in each of the developing units and a member also included in the developing unit and contacting or adjoining the developer carrier in a predetermined positional relation are mounted on the second side plates.
