摘要： An image forming unit includes four photoconductors, a belt extended around a driving roller and an extension-cum-primary transfer roller. Three primary transfer rollers sandwich the belt in association with a corresponding photoconductor. The extension-cum-primary transfer roller serves both as an extension roller and a primary transfer roller.

摘要： The developing apparatus has: a development sleeve; a supply roller; a toner hopper; a stirring member; and a partition member. The partition member and a regulating blade form a space. The supply roller supplies toner to lower part of the space. Thereby, toner present in the proximity of the development sleeve circulates smoothly. Therefore, the following situation will be prevented: 1) since same toner particles are repeatedly stressed by regulation of the regulating blade, toner particles crack; 2) cracked tiny particles of toner melt and adhere to the development sleeve; or 3) the regulating blade gets stiff due to the cracked toner adhering thereto. Further, since constant amount of toner is always collected within the space, appropriate pressure of toner is applied at the regulating position when the regulating blade takes toner into the space.
摘要翻译：显影装置具有：显影套筒; 供应辊; 墨粉盒; 搅拌构件; 和分隔构件。分隔构件和调节叶片形成空间。供应辊将墨粉供应到下部空间。因此，存在于显影套筒附近的调色剂平稳地循环。因此，可以防止以下情况：1）由于相同的调色剂颗粒通过调节刮板的调节反复受到压力，调色剂颗粒破裂; 2）破碎微粉的微粒熔融并附着在显影套上; 或3）由于粘附有破裂的调色剂，调节片变硬。此外，由于恒定量的调色剂总是在空间内收集，所以当调节片将调色剂吸入空间时，在调节位置施加适当的调色剂压力。

摘要： An one-component developing device includes an electrically conductive member which is located in a region extending from a position downstream, with respect to a moving direction of a surface of a toner carrying member, to a developing region, and is in contact with the surface of the toner carrying member. A surface of the electrically conductive member contacting the developing sleeve is formed of material, of which charge polarity is shifted to the same polarity side as a regular charge polarity of the toner in view of charge series, and which contains highly conductive material dispersed therein.
摘要翻译：单组分显影装置包括导电构件，该导电构件位于从相对于调色剂承载构件的表面的移动方向的下游位置延伸到显影区域的区域中，并且与表面接触的调色剂承载构件。与显影套筒接触的导电构件的表面由材料形成，其电荷极性从电荷序列的角度偏移到与调色剂的常规电荷极性相同的极性侧，并且其包含分散在其中的高导电性材料。

摘要： An electrostatic latent image developing device includes a rotatable developing sleeve for providing an electrostatic latent image formed on a photoreceptor with a toner so as to develop the latent image into a visual image, and a toner regulating blade which contacts at one surface with the developing sleeve so that the toner is regulated and then formed into a thin layer. The toner regulating blade has, in a surface confronting the toner bearing member, a bevelled portion which forms a wedge shaped space in a upstream side of a contact region of the blade and the developing sleeve with respect to a direction of a movement of the developing sleeve. Further, the toner regulating blade has chamfered portions in the bevelled portion at both sides thereof. Therefore, the sleeve bears a toner thin layer having a constant density.
