摘要： 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.

摘要： A control portion obtains a first difference in a movement amount between paper passing period and paper non-passage period of a transfer belt, and determines whether or not a first absolute value thereof is a first threshold value or more. In a case where the first absolute value is the first threshold value or more, a transfer belt unit positional adjustment motor is driven to adjust a first angle with respect to a first direction of a transfer belt unit with respect to a photoreceptor drum. In a case where the first absolute value is less than the first threshold value, a second absolute value of a second difference between a movement amount and a designed value set in advance of the transfer belt is obtained, and whether or not the second absolute value is a second threshold value or more is determined. When the second absolute value is less than the second threshold value, the processing is finished, and when the second absolute value is the second threshold value or more, a second angle with respect to a second direction orthogonal to the first direction of the driving roller with respect to the photoreceptor drum is adjusted so as to be less than the second threshold value by a driving roller positional adjustment motor.

The meandering prevention member is attached on one widthwise end of a circumferential surface of the belt body such that one widthwise end of the folded trace is covered thereby and the opposite longitudinal ends of the meandering prevention member abut each other in a rotating direction of the belt body. An abutting portion at the opposite ends of the meandering prevention member is arranged at a position displaced from the folded trace by a specified distance in the rotating direction of the belt body.

摘要： A belt is entrained on a plurality of rollers and runs when the rollers are driven to rotate. A bead is attached to the belt and prevents the belt-like member from running crooked. The bead includes a first layer formed of a first material having a first hardness and a second layer formed of a second material having a second hardness. The second layer is laminated on the first layer. The bead is attached to the belt with the first layer being closer to the belt than the second layer. The first material and the second material expand simultaneously with temperature and humidity, and the first material and the second material contract simultaneously with temperature and humidity. The first hardness is higher than the second hardness.

摘要： A fuser has a heater housing extending through an endless belt with end caps on the housing adjacent to opposite lateral sides of the belt. The end caps have inner flanges spaced radially outward from a center portion and radially inward from the opposite marginal side edge portions of the belt so as to define clearance therebetween. Protuberances on the inner flanges of the end caps project toward opposite marginal edge portions of the belt and are circumferentially spaced apart to reduce belt skew relative to the end caps by either decreasing the surface area of contact of the inner flanges with the opposite marginal side edge portions of the belt to reduced surface areas of contact of protuberances therewith or decreasing the radial height of the clearance between the inner flanges and opposite side edge portions of the belt to the reduced radial height between the latter and the protuberances.
