    • A developing device for developing an electrostatic latent image with a two-component developer comprises a developer container (46) including a developer-accumulating chamber (50), and a developer-agitating chamber (56) provided above the developer-accumulating chamber. A communication passage (64) is provided between the developer-agitating chamber and the developer-accumulating chamber, and is opened to the developer-agitating chamber to define an overflow opening for the developer. The device also comprises a developer-carrying body (48) provided in the developer-accumulating chamber of the developer container, and the developer-carrying body is exposed to face an electrostatic latent image carrying body, and brings the developer from the developer-accumulating chamber to a facing zone therebetween for development of an electrostatic latent image formed on the electrostatic latent image carrying body. The device further comprises a developer-lifting means (68, 68', 70) for lifting the developer, brought to the facing zone by the developer-carrying body, to the developer-agitating chamber of the developer container, and a developer-agitating means (58) for agitating the developer in the developer-agitating chamber of the developer container, a part of the developer agitated by the developer-agitating means being fed to the developer-accumulating chamber through the overflow opening and the communication passage.
    • 用双组分显影剂显影静电潜像的显影装置包括显影剂容器(46),显影剂储存室(50)和显影剂搅拌室(56),设置在显影剂积聚室的上方。 连通通道(64)设置在显影剂搅拌室和显影剂储存室之间,并且向显影剂搅拌室打开以形成用于显影剂的溢流开口。 该装置还包括设置在显影剂容器的显影剂储存室中的显影剂承载体(48),并且显影剂承载体暴露于面对静电潜像携带体,并使显影剂从显影剂积聚 室到其间的面对区域,用于显影形成在静电潜像承载体上的静电潜像。 该装置还包括用于将显影剂提升到显影剂携带体的面向区域的显影剂提升装置(68,68',70)到显影剂容器的显影剂搅拌室,并且显影剂搅拌 用于搅拌显影剂容器的显影剂搅拌室中的显影剂的装置(58),由显影剂搅拌装置搅动的显影剂的一部分通过溢流开口和连通通道被供给到显影剂积聚室。

    • A clamp device which can be easily attached/detached and securely fixed to a board. In order to attach an electric wire bundle clamp to the board, a leg portion of the clamp is inserted in a circular hole of an attachment hole provided in the board, while engaging protruding pieces of the clamp are similarly inserted into notches of the board. Subsequently, the electric wire bundle clamp is rotated 90 degrees, allowing a portion of the board around the circular hole to be held between a base on the surface of the board and the engaging protruding pieces contacting on the underside of the board. Once rotated an engagement protrusion comes to rest in an engagement hole of the board preventing further rotation and firmly fixing the clamp device relatively to the board.
    • 夹紧装置,可以容易地安装/拆卸并牢固地固定在板上。 为了将电线束夹持件附接到基板上,夹具的腿部插入到设置在基板中的安装孔的圆形孔中,同时将夹具的突出片类似地插入到板的凹口中。 随后,电线束夹具旋转90度,使得围绕圆形孔的板的一部分被保持在板的表面上的基座和与板的下侧接触的接合突出件之间。 一旦旋转,接合突起停止在板的接合孔中,防止进一步旋转并且相对于板牢固地固定夹持装置。

    • A developing portion forms a toner image, which corresponds to a recording image, with a toner which has been electrically charged to a predetermined electrical potential. A transfer portion, to which an electric potential, different from the electric potential of the toner image, is applied, transfers the toner image onto a recording medium. A first transfer-electric-potential applying portion applies a transfer electric potential to the transfer portion. A carrying portion carries the recording medium so as to cause the recording medium to pass by the transfer portion. A second transfer-electric-potential applying portion sets the recording medium and the carrying portion to cause the recording medium and the carrying portion to have a predetermined electric potential corresponding to the transfer electric potential of the transfer portion.
    • 显影部分与已经充电到预定电位的调色剂形成对应于记录图像的调色剂图像。 将不同于调色剂图像的电位的电位的转印部分转印到记录介质上。 第一转印电位施加部分向转印部分施加转印电位。 携带部分携带记录介质,以使记录介质通过转印部分。 第二转印电位施加部分设置记录介质和承载部分,使记录介质和承载部分具有与转印部分的转印电位对应的预定电位。
