    • A process cartridge includes an image bearing unit, a developing unit, and first and second positioning members. The image bearing unit includes a photoconductor, and a photoconductor case accommodating the photoconductor. The developing unit detachably combined with the image bearing unit includes a developer case containing a developer, a developing roller carrying the developer. The first and second positioning members are respectively disposed at each side of the photoconductor case and the developer case when the photoconductor case and the developer case are attached in combination, and is configured to position the developing roller and the photoconductor so as to regulate a gap formed between the developing roller and the photoconductor to a predetermined distance.
    • 处理盒包括图像承载单元,显影单元以及第一和第二定位构件。 图像承载单元包括光电导体和容纳光电导体的光电导体壳体。 与图像承载单元可拆卸地组合的显影单元包括容纳显影剂的显影剂盒,承载显影剂的显影辊。 第一和第二定位构件分别设置在光电导体壳体的两侧,并且当感光体壳体和显影剂盒体组合安装时,显影剂壳体被构造成定位显影辊和光电导体,以便调节间隙 在显影辊和感光体之间形成预定距离。

    • An image forming apparatus includes a latent image bearer, an electric charging member to electrically charge the latent image bearer uniformly while forming an electric charging nip therebetween by contacting the latent image bearer. A value obtained by dividing a moment of inertia of area of the latent image bearer by the cube of length thereof ranges from about 0.000058 [mm] or more to about 0.000145 [mm] or less. A width of the electric charging nip in a direction of rotation at longitudinal ends of the latent image bearer is larger than that at a longitudinal center thereof. A difference between the width of the electric charging nip in the direction of rotation at the longitudinal ends of the latent image bearer and that at the longitudinal center thereof is larger than an amount of deformation of the latent image bearer generated during rotation at the longitudinal center thereof.
    • 图像形成装置包括潜像承载体,电荷充电构件,其通过使潜像载体接触而在其间形成充电间隙而均匀地对所述潜像载体进行电荷充电。 通过将潜像载体的面积的惯性矩除以其长度方块而获得的值为约0.000058 [mm]以上至约0.000145 [mm]以下。 在潜像载体的纵向端部处的旋转方向上的充电辊隙的宽度大于其纵向中心处的宽度。 在潜像承载体的纵向端部和纵向中心的旋转方向上的充电辊隙的宽度之间的差异大于在纵向中心处旋转期间产生的潜像载体的变形量 其中。
