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 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.

摘要： A belt positioning system for positioning 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 tapered flange. The tapered flange is operatively connected to an axial end of a specific one of the plurality of generally parallel rollers, and includes a generally planar contact surface and an angled guide surface. The generally planar contact surface extends generally perpendicular to the axial direction to contact an adjoining edge of the belt. The angled guide surface extends radially outward from the contact surface and has a diameter increasing outward in the axial direction.

摘要： An endless belt is extended over extending rollers, and carries a toner image transferred from an image carrier or a transfer sheet. The endless belt includes a front-side reinforcing member and a rear-side reinforcing member, and a guide member for preventing meandering fixed over an approximately entire circumference on the rear-side reinforcing member. The extending rollers include a step portion provided in an end area in an axial direction facing to the rear-side reinforcing member, which has a diameter smaller than a center area in the axial direction. The front-side reinforcing member has a width wider than a width of the rear-side reinforcing member.

摘要： A method for evaluating an electric resistance member of an image forming apparatus which can maintain good image quality, without the occurrence of transfer defects such as insufficient transfer, even in a long-term use. An intermediate transfer belt of the image forming apparatus, which is evaluated based on a fluctuation characteristic of the resistivity in a period of continuous voltage application, is used. The absolute value Δρs of the amount of changes in the surface resistivity of the intermediate transfer belt within 2 seconds to 100 seconds from the beginning of voltage application is 0.3 [Log(Ω/)] or less, when the surface resistivity ρs is measured by applying a voltage of 500 V. The absolute value Δρv of the amount of changes in the volume resistivity within 2 seconds to 100 seconds from the beginning of voltage application is 0.5 [Log(Ω·cm)] or less, when the volume resistivity ρv is measured by applying a voltage of 200 V.
