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： An image forming apparatus includes a belt member to convey a sheet-formed medium, a belt supporting device to support the belt member, and a plurality of recording units including rotating image bearing members arranged in a conveying direction of the sheet-formed medium by the belt. The image forming apparatus performs processes of (1) forming a latent image on a surface of each image bearing member, (2) developing each latent image into a toner image with toner, and (3) then transferring each toner image onto the sheet-formed medium carried on the belt. A detection device detects arbitrary toner image patterns formed at the plurality of recording units and then directly transferred onto the belt, for obtaining information about density and placements of images without the toner patterns being deteriorated by contacting following downstream recording units.

摘要： A color image forming apparatus includes a plurality of image forming sections independent of each other. The image forming sections store respective toner of different colors that are chargeable to the same polarity. All the toner are implemented by the same binder resin and provided with the same particle size distribution. Further, developing units each storing toner of particular color are identical in specification. When two-ingredient type developers are used, the developers contain an identical carrier. The apparatus recycles the toner of different colors to the respective developing units. The alien color toner collected in each developing unit is prevented from remaining by being chargeable to the same polarity.

摘要： An image forming apparatus includes a heating device, a recording medium ejector, a recording medium tray, an outer wall having an intake, and a filter. The heating device heats a recording medium having an image on one side of the recording medium. The recording medium ejector ejects the recording medium with the one side facing downward. On the recording medium tray, the recording medium ejected by the recording medium ejector is stacked. The intake is open toward the recording medium tray and is disposed at a position below the recording medium ejector. At the position, a maximum amount of recording media placeable on the recording medium tray does not cover at least a part of the intake. The filter collects foreign substances in air sucked from the intake.
