A rotary type developing device has a hollow cylindrical casing rotatable around a shaft having a central portion for rotation. The developing device includes a casing which is rotated in a predetermined direction, and four partitions which divide the casing to make four developing units which extend radially outward from the shaft. A toner storing section or hopper is provided on one side of the developing device, i.e., on a front side of the image forming apparatus, and a toner cartridge is detachable from a top of the hopper, and the toner cartridge is exchanged when an end signal of the toner is detected by a sensor in the casing. The toner hopper is filled by new toner from the toner cartridge, and the toner is carried by conveyor members, which control an amount of the toner in the casing, and a supply roller supplies the toner to a developing roller.

The weight ratios of (A) to (B) to (C) to (D) is 15-55:15-55:5-40: 5-45.The treating material is capable of absorbing liquids from excretions quickly, forming into clumps when absorbing liquid and maintaining the shape of the clump even when handled for removal.

Abstract: A developing device capable of obviating the cohesion of toner and reducing the amount of dead toner is disclosed. The device has a developing unit accommodating a first and a second screw therein. The first and second screws extend from the toner hopper to the other longitudinal end of the developing unit in parallel to a developing roller and a supply roller. The first screw feeds toner from a toner hopper to a developing section. The second screw collects toner not contributed to development from the developing section and returns it to the first screw for recirculation. In this configuration, the collected toner and dead toner aggregating in the lower portion of the developing unit are forcibly moved to the developing section. The direction in which the screw portion of the second screw is inclined may be partly reversed to form a reverse transfer portion. Alternatively, a part of a casing adjoining the hopper may be implemented as a slant.

Abstract: A joint having an OLDHAM state coupling at a leading edge thereof is held movably in a direction which is parallel to a joint axis at a full-color printer body. A coupling gear is substantially connected to a developing roller disposed in each mono-color developing unit, which makes up a revolving type developing device. At the time of developing by one of the mono-color developing units, the joint is capable of moving in parallel to the axis of the joint in the state of being rotated toward the coupling. A projection is further provided at the leading edge of the coupling, and a claw is further provided at the end of the coupling gear. Thereby, smooth engagement between the coupling gear and the coupling is made by the help of the OLDHAM state coupling, the projection and the claw. As a result, the driving force is transmitted from the joint to the developing roller disposed in the developing unit, so that the developing roller can rotate at a predetermined speed and direction.

Abstract: In an image forming apparatus, a rotary developing device effects development by revolving a plurality of developing sections around a rotary shaft until any one of them reaches a developing position where it faces an image carrier. Cartridges are respectively mounted to hoppers included in the developing sections. Guides are provided on the inner periphery of each cartridge in order to guide toner, moving due to the revolution or the developing device, toward a toner outlet formed in the cartridge. Even when the amount of toner remaining in the cartridge is small, the entire toner is replenished into the associated hopper and fully consumed.

Abstract: A rotary developing device for an image forming apparatus includes a plurality of rotary developing units accommodating a powder developer and being supported around a common axis, and a plurality of toner cartridges corresponding to the plurality of rotary developing units for supplying toner to the plurality of rotary developing units. Each rotary developing unit is moved to a developing position facing a latent image carrier by the rotation about the common axis and an electrostatic latent image formed on the latent image carrier is developed. The plurality of toner cartridges are connected with the plurality of rotary developing units so as to rotate together, and a toner outlet of the toner cartridge is disposed such that the toner is supplied to the respective rotary developing unit by the force of gravity on the toner accommodated in the respective toner cartridge at the time of rotational movement of the toner cartridge.

Abstract: A color image forming apparatus of the type having a photoconductive belt for forming a latent image thereon electrostatically. The latent image is developed to turn out a corresponding toner image. The toner image is transferred from the photoconductive belt to an intermediate transfer belt. Such a procedure is repeated to form a composite color image on the intermediate belt. The color image is transferred from the intermediate belt to a recording medium. Any point on the intermediate belt in the direction of rotation and any points on drive rollers assigned to the two belts, respectively, in the direction of rotation are held in the same positional relation to a stationary member every time the intermediate belt completes one rotation.

A one-way transmission mechanism is located on a drive transmission path extending from the drive source to the rotary body for preventing a drive force from being imparted from the rotary body to the drive source. When the rotary body tends to rotate or vibrate due to an external force or vibration, the rotation or vibration is prevented from reaching the drive source.
