    • A grid electrode, which can be included in a scorotron charger for an image forming apparatus or a process cartridge, includes a thin plate member containing multiple apertures and linear patterns, and fitting members. The multiple apertures are disposed facing a charge wire, and the linear patterns are formed in the longitudinal direction of the grid electrode and disposed at equally-shaped intervals in a lateral direction thereof to cause the fitting member to apply tension in the longitudinal axis of the thin plate member at end portions in the lateral direction of the fitting member. The fitting members engage hooks mounted on the scorotron charger at both ends of the grid electrode in a longitudinal direction of the thin plate member containing the multiple apertures and linear patterns.

    • An image forming apparatus includes an image bearing member having a photoconductive surface including an image forming area configured to bear an electrostatic latent image and a non-image forming area. A charging roller has a circular cross section with a first radius, the charging roller including a metallic core having a same rotational axis as the charging roller and a charging surface configured to charge the photoconductive surface of the image bearing member. A pair of gap forming members is disposed on longitudinal ends of the charging surface of the charging roller and is configured to contact longitudinal ends of the image bearing member to form a gap at least between the image forming area of the photoconductive surface of the image bearing member and the charging surface of the charging roller, each of the gap forming members having a circular cross section with a second radius such that a ratio of the second radius to the first radius is substantially constant through an entire rotational phase of the charging roller.
    • 图像形成装置包括具有感光面的图像承载部件,该感光体表面具有构成为承载静电潜像和非图像形成区域的图像形成区域。 充电辊具有第一半径的圆形横截面,充电辊包括具有与充电辊相同的旋转轴线的金属芯和被配置为对图像承载部件的光电导表面充电的充电表面。 一对间隙形成构件设置在充电辊的充电表面的纵向端部上,并且构造成接触图像承载构件的纵向端部,以至少在图像承载体的光电导表面的图像形成区域之间形成间隙 构件和充电辊的充电表面,每个间隙形成构件具有圆形横截面,具有第二半径,使得第二半径与第一半径的比率通过充电辊的整个旋转相位基本上恒定。
