Abstract: A belt device includes a plurality of support rotators, a belt, a cleaner, and a rotator inclination unit. The belt is looped around the plurality of support rotators and moves according to rotation of the plurality of support rotators. The cleaner contacts a surface of the belt to remove foreign substances. The rotator inclination unit inclines an inclined support rotator that is at least one of the plurality of support rotators. The cleaner is disposed in contact with a portion of the belt stretched taut between the inclined support rotator and another support rotator. A pushing amount of the cleaner relative to the belt varies according to inclination of the inclined support rotator and is smallest in a state in which the inclined support rotator is not inclined by the rotator inclination unit.

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.

Abstract: A belt device incorporatable in an image forming apparatus includes an endless belt, multiple belt tension rollers disposed in contact with an inner surface of the endless belt, a rotary cleaning member to contact a belt wound area of the endless belt facing an opposing roller to form a cleaning nip between the rotary cleaning member and the endless belt and rotate the rotary cleaning member in a direction opposite the belt moving direction within the cleaning nip, and a voltage applier. The cleaning nip is formed by offsetting a center of the cleaning nip upstream from a center of the belt wound area of the endless belt in the belt moving direction and by at least contacting the rotary cleaning member in a range from the belt wound area to a tensioned belt area located upstream from the belt wound area in the belt moving direction.

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 stationary member, a slidable member, and a biasing mechanism. 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 stationary member is fixed in position adjacent to the roller shaft to define a first interfacial surface therealong. The slidable member is co-movably coupled with the roller shaft to define a second interfacial surface therealong inclined relative to the axial direction. The biasing mechanism is connected to the roller shaft to press the slidable member against the stationary member.
