摘要： Disclosed is a latent image carrier provided with a structure in which noise generation can be prevented and an opposing gap between a charging device and the latent image carrier is prevented from being altered as well, whereby change in charging property is not generated and the formation of an abnormal image can be prevented in the case where a thin cylindrical body is employed as the latent image carrier. The latent image carrier is capable of forming an electrostatic latent image which corresponds to an image by means of optical writing after which a photosensitive layer has been uniformly charged. The latent image carrier is characterized in that the latent image carrier is formed of a thin cylindrical body and deformation preventing member is disposed in an interior portion thereof along the circumferential and axial directions.

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.
摘要翻译：公开了能够消除调色剂的内聚力并减少死色调色剂量的显影装置。该装置具有容纳第一和第二螺丝的显影单元。第一和第二螺丝平行于显影辊和供给辊从调色剂料斗延伸到显影单元的另一纵向端。第一螺杆将调色剂从调色剂料斗送入显影部分。第二螺丝收集未显影的调色剂并将其返回到用于再循环的第一螺杆。在这种结构中，收集的调色剂和在显影单元的下部中聚集的死色调剂被强制地移动到显影部分。第二螺钉的螺纹部分倾斜的方向可以部分地反向以形成反向转移部分。或者，与漏斗相邻的壳体的一部分可以实现为倾斜。反向转印部分或倾斜剂更强制地再循环调色剂。

摘要： A developing device for an image forming apparatus and using a one component type developer. The developer is transferred from a developer supply member to a developer carrier which are so rotated as to move in the same direction at a position where they contact each other. This prevents the developer from a toner storing section from directly reaching part of the developer carrier having moved away from the contact position despite the movement of the developer supply member. Conductive portions connected to ground and dielectric portions each having a small area are distributed regularly or irregularly on the surface of the developer carrier. Such a surface of the developer carrier is charged by friction by the developer supply member with the result that a great number of microfields are formed in the vicinity of the developer carrier. The microfields allow only the developer sufficiently charged by friction at the contact position to form multiple layers on the surface of the developer carrier. Consequently, the toner with a desired amount of charge and containing a minimum of uncharged toner can form multiple layers on the developer carrier and is transferred to an image carrier.
