摘要： A structure which increases positioning precision of a blade member to a rotating member, an image forming apparatus, and a method of manufacturing a unit frame. A first reference surface of a boss provided on a surface of a frame to which a blade is contacted is formed by a first mold that forms a positioning hole for positioning a rotating member. The first reference surface supports the blade member to prevent the blade member from moving to a weight direction. With this arrangement, there is no manufacturing error of the first reference surface due to a mold assembling error. As a result, precision of positioning the blade member to the rotating member can be increased.

摘要： A charging device includes a charging roller, a drive transmission device, and a charging roller cleaner. The charging roller opposes an image carrier driven to rotate and rotates to charge the image carrier. The charging roller cleaner contacts the charging roller to clean the charging roller. The drive transmission device transmits torque from the image carrier to the charging roller, and includes an image carrier gear and a driven gear. The image carrier gear and the driven gear form a gear train to drive the charging roller in response to rotation of the image carrier. The charging roller cleaner is disposed facing a rear surface of the charging roller to prevent displacement of the charging roller due to a force generated by a pressure angle formed between the image carrier gear and the driven gear when the charging roller rotates in response to rotation of the image carrier.

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： A damping member is fitted in the hollow cylindrical core of a photoconductive drum. The damping member is implemented as a hollow cylinder having one end thereof closed by an end wall. A jig is inserted into the damping member and caused to insert the damping member into the drum by pressing the end wall. The damping member is therefore easily fitted in the drum. The damping member is formed of an elastic material for damping vibration.
