Abstract: A blade of a cleaning device includes two surfaces: an upstream side surface and a downstream side surface. The two surfaces adjoin each other with respect to a contact edge of the blade. The upstream side surface has a longer dimension in the direction orthogonal to the contact edge than that of the downstream side surface. A horizontal portion of a blade holder that restricts a warp in the blade is bonded on an opposed surface to the upstream side surface of the blade. The blade is held via the horizontal portion with a vertical portion of the blade holder supported by the main body of the cleaning device in a downstream of a normal line to a contact point on a photoconductor surface in contact with the contact edge, in the photoconductor-surface moving direction.

Abstract: An image forming apparatus includes units for electrostatically charging a surface of an image carrier, exposing the surface according to image data to write a latent image, supplying a toner to the latent image to form a visible image, and transferring the visible image from the surface to another surface. A rotatable brush roller and a cleaning blade in contact with the surface removes remaining toner. Another brush roller rotates and scrapes lubricant to apply the lubricant to the surface. The image forming apparatus has a lubricant consumption of 0.1 gram to 1.2 grams per 1,500 meters of a traveling distance of the image carrier.

Abstract: A belt device for an image forming apparatus, includes an endless belt; a first and second support rollers, each including a rotary shaft, that support the belt with tension; a contacted member that contacts the belt; a shaft displacement device to displace any of the rotary shafts of the support rollers; and a main rotary shaft disposed at a side of the rotary shaft of the first support roller moved by the shaft displacement device along a stretching direction of the stretched surface of the endless belt that the contacted member contacts, relative to a contact portion between the endless belt and the contacted member, and at an opposite side of the contacted member in a direction perpendicular to the stretching direction of the endless belt. As the first support roller and the second roller rotate about the main rotary shaft, the endless belt is separated from the contacted member.

Abstract: An image forming apparatus includes a toner image forming device to form a toner image on a rotatable toner image bearer, a looped belt to carry a recording medium, a support roller to rotate the belt, a pressing member to press the belt against the toner image bearer, a transfer electric field generator to form an electric field to transfer the toner image onto the recording medium, and a contact member to contact an end surface of the belt as the belt moves to one side in a belt width direction. The belt includes a first portion pressed against the toner image bearer by the pressing member and a second portion adjoining the first portion. A relative position of the support roller relative to the toner image bearer and the pressing member is determined such that the second portion of the belt contacts the toner image bearer.

Abstract: A belt tracking system for controlling the lateral position of a movable belt entrained about a plurality of generally parallel rollers for moving in a trans-axial direction perpendicular to an axial direction in which the rollers extend parallel to each other includes a roller shaft, a slidable member, and a rotation restrictor. The roller shaft extends outward in the axial direction from an axial end of a specific one of the plurality of generally parallel rollers. The slidable member is slidably disposed around the roller shaft to move along the roller shaft as the belt moves laterally outward in the axial direction. The rotation restrictor is disposed adjacent to the slidable member to restrict rotation of the slidable member around the roller shaft.
