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

    Abstract: An electrostatic latent image developing apparatus supplies toner to a latent image carrier such as a drum-shaped photosensitive body to visualize a latent image formed thereon. The toner is supplied by a rotating drum-shaped toner carrier having a portion confronting the photosensitive body adjacent thereto and another portion held in contact with toner contained in a toner container. The toner is electrostatically attracted to the toner carrier and transferred therefrom to the photosensitive body. The toner on the toner carrier is regulated into a thin toner layer by a toner layer regulating member that is resiliently held in sliding contact with the toner carrier. To prevent toner deposits from being attached to the toner layer regulating member, the toner layer regulating member is made of a material adapted to wear with the attached toner. In order to provide the toner layer regulating member with an ability to triboelectrically charge toner, whether chargeable to a polarity (-) or (+), or to control the amount of electricity on toner chargeable to a polarity (-) or (+) and prevent toner deposits from being attached to the toner layer regulating member, another material to control the amount of electricity on toner is mixed in the material which can be worn with the attached toner.

    Abstract: 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.

    Abstract: 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.

    Abstract translation: 在图像形成装置中，显影装置邻近带状感光构件设置。 旋转型显影装置具有中空圆筒形壳体，该中空圆柱形壳体可围绕具有用于旋转的中心部分的轴旋转。 显影装置包括沿预定方向旋转的壳体和分隔壳体以形成从轴径向向外延伸的四个显影单元的四个隔板。 调色剂存储部分或料斗设置在显影装置的一侧，即在图像形成装置的前侧，并且调色剂盒可从料斗的顶部拆卸，并且调色剂盒在末端 调色剂的信号通过壳体中的传感器检测。 墨粉盒由调色剂盒中的新调色剂填充，调色剂由传送部件承载，传送部件控制壳体中的调色剂量，供给辊将调色剂供给显影辊。 因此，该装置始终向调色剂供应辊和显影辊提供所需量的调色剂。 这提供了一种具有很大布局自由度的图像形成装置，其需要相对于光导元件的最小截面空间，因此具有微型构造。 此外，如果适当地选择第一和第二输送器构件的输送量，则不会诉诸于复杂的控制，所以在长度方向上均匀的显影剂分布被保证。
