摘要： 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.

摘要： 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. The reverse transfer portion or the slant recirculates the toner more forcibly.

摘要： In an image forming apparatus, a developing device is disposed adjacent to a belt-like photosensitive member. 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. Therefore, the device supplies a required amount of toner to a toner supply roller and a developing roller at all times. This provides an image forming apparatus with a great freedom of layout which needs a minimum sectional space relative to a photoconductive element and which, therefore, has a miniature configuration. Also, if amounts of transport of first and second conveyor members are adequately selected, a uniform developer distribution in a longitudinal direction without resorting to a complicated control is insured.

摘要： 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.

摘要： An electrophotographic color image forming apparatus is disclosed which allows a photoconductive element and an intermediate transfer belt, which are expendables, to be removed from the body thereof at the same time. This promotes easy replacement, inspection and so forth of expendables. The photoconductive element and intermediate transfer belt can be replaced substantially at the same period, reducing the frequency of replacement of expendables. A cartridge including the photoconductive element can be replaced with a minimum of component parts wasted, thereby enhancing the cost performance of the apparatus. Moreover, when a cover hinged to the body of the apparatus is opened, various units can be removed one after another, a unit around which the greatest space is available being first.

摘要： A composite scanning tunneling microscope comprises a first objective optical system for collimating an optical flux from a sample, a second objective optical system for condensing the optical flux thus collimated, and a transparent member disposed between the first and the second objective optical systems. A through hole is perforated along an optical axis in the center of the first objective optical system. A tube scanner member has a probe for detecting a tunnel current disposed at one end thereof. The tube scanner member passes through the hole of the first objective optical system without a contact therewith. The other end of the tube scanner member is fixed to the transparent member. The tube scanner member fixed to the transparent member is separate from and independent of an optical microscope, so that a tunnel current may stably be detected without influences on the probe from vibrations of the optical microscope.
