    • An image forming apparatus, includes: an image carrier that carries an electrostatic latent image; a toner carrier roller that is provided, on a surface thereof, with a plurality of convex sections and a concave section which surrounds the convex sections, is shaped approximately like a cylinder, is arranged opposed to the image carrier, and rotates while carrying a toner layer of charged toner on the surface thereof; a bias applier that applies a developing bias voltage to the toner carrier roller; a toner collector that collects the toner carried on the surface of the toner carrier roller at a place downstream to an opposed position facing the image carrier in a rotation direction of the toner carrier roller; a seal member that is interposed between the toner carrier roller and the toner collector, and abuts on the surface of the toner carrier roller to prevent leakage of toner from the toner collector; and a controller that is adapted to perform a toner removal operation which removes toner adherent to the seal member by rotating the toner carrier roller while the toner carrier roller abuts on the seal member, in a condition that at least a part of respective surfaces of the convex sections do not carry toner so as to be exposed.
    • 一种图像形成装置,包括:承载静电潜像的图像载体; 在其表面上设置有多个凸部和围绕凸部的凹部的调色剂承载辊成形为大致像圆筒一样,与图像载体相对设置,并且在携带调色剂的同时旋转 其表面上带电的调色剂层; 偏置施加器,其将显影偏压施加到调色剂承载辊; 调色剂收集器,其在调色剂承载辊的旋转方向上在与图像载体相对的相对位置下游的位置处收集在调色剂承载辊的表面上承载的调色剂; 介于所述调色剂承载辊和所述调色剂收集器之间的密封构件,并邻接所述调色剂承载辊的表面以防止调色剂从所述调色剂收集器泄漏; 以及控制器,其适于执行调色剂去除操作,其在所述调色剂承载辊抵接在所述密封构件上的同时通过使所述调色剂承载辊旋转而去除附着于所述密封构件的调色剂,所述调色剂承载辊在所述调色剂承载辊的至少一部分 凸部不携带调色剂以露出。

    • The invention provides, as an aspect thereof, an image formation apparatus that includes: an image carrier that carries a latent image; a toner carrier that has, on a surface of the toner carrier, a concave portion arrayed in a regular pattern so as to carry toner, and develops the latent image that is carried on the image carrier by means of the toner carried in the concave portion; and a voltage application section that applies a development voltage to the toner carrier for the purpose of the development of the latent image. In the configuration of an image formation apparatus according to the above-described aspect of the invention, immediately after that the toner carrier has developed the latent image, which is carried on the image carrier, by means of the toner carried in the concave portion in response to the application of the development bias to the toner carrier by the voltage application section, at least one layer of the toner remains carried in the concave portion.
    • 本发明作为其一个方面提供了一种图像形成装置,其包括:承载潜像的图像载体; 在调色剂载体的表面上具有排列成规则图案的凹部以便携带调色剂的调色剂载体,并且借助于承载在凹部中的调色剂显影承载在图像载体上的潜像 ; 以及为了显影潜像的目的而向显影剂载体施加显影电压的电压施加部分。 在根据本发明的上述方面的图像形成装置的配置中,紧接着,调色剂载体已经通过在凹部中承载的调色剂显影载体在图像载体上的潜像 响应于通过电压施加部分将显影偏压施加到调色剂载体,至少一层调色剂保留在凹部中。
