    摘要： A charging device, an image forming apparatus including the charging device, an image carrier unit including the charging device and a charging roller, which faces a body to be charged and is applied with a voltage, are disclosed. The charging roller includes a metallic core and an elastic member covering the core. Films are respectively wrapped around and adhered to the opposite end portions of the elastic member. Springs press the charging roller toward a body to be charged, causing the elastic member to deform due to compression. The maximum deformation of the films, which deform along the outer periphery of the elastic member, is selected to be smaller than the thickness of each film in the radial direction of the charge roller. A gap is therefore formed between the elastic member and the body to be charged. This prevents the portion of the elastic member, which corresponds to an image forming region, other than opposite end portions from contacting the surface of the body to be charged.

    摘要翻译： 公开了一种充电装置，包括充电装置的图像形成装置，包括充电装置的图像载体单元和充电辊，其面向要充电的主体并施加电压。 充电辊包括金属芯和覆盖芯的弹性构件。 膜分别缠绕并粘附到弹性构件的相对端部。 弹簧将充电辊朝向要充电的主体按压，导致弹性构件由于压缩而变形。 沿着弹性构件的外周变形的膜的最大变形选择为小于充电辊的径向上的每个膜的厚度。 因此，弹性构件和被充电体之间形成间隙。 这防止弹性构件对应于除了相对端部以外的图像形成区域的部分与身体的表面接触的部分被充电。

    摘要： Disclosed is an image forming device including a fixing unit that fixes a first image to be fixed onto a sheet, the first image to be fixed being supported on the sheet, a target fixing temperature varying unit that varies a target fixing temperature during a time period in which a fixing process is performed, and a gradation processing unit that applies a gradation process to first image information. The target fixing temperature varying unit varies the target fixing temperature for the sheet of the recording medium to which the fixing process is applied, depending on presence or absence of a halftone process, and depending on a type of the gradation process to be utilized.
