Abstract:
A stretching roller for stretching an intermediate transfer belt is tiltably disposed, and includes a sliding ring unrotatably disposed at both axial ends of a roller portion. The intermediate transfer belt winds and slidably rotates around the sliding ring. The sliding ring has a tapered portion inclined so that the outer diameter increases toward the axial end side of the stretching roller. The tapered portion is formed so that the inclination angle with respect to the central axis of the stretching roller differs at least in part in the circumferential direction.

Claim (Index 1):
A belt conveyance apparatus comprising:\n an endless belt member configured to rotate; and a stretching roller configured to stretch the belt member and tilt to make the belt member movable in a lateral direction intersecting with a rotational direction of the belt member, the stretching roller including a roller portion configured to rotate together with the belt member, and a sliding portion, that does not rotate together with the belt member, disposed at both ends of the roller portion with respected to a rotating axis line of the roller portion and configured to allow the belt member to slide, wherein a distance between an outer surface of the sliding portion at a first position and an outer surface of the roller portion with respect to a radial direction of the roller portion in a first predetermined cross section including the rotating axis line of the roller portion is larger than a distance between an outer surface of the sliding portion at a second position and an outer surface of the roller portion with respect to the radial direction in the first predetermined cross section, the second position is inside the first position with respect to the rotating axis line of the roller portion, wherein when a distance between an outer surface of the sliding portion and an outer surface of the roller portion with respect to a radial direction of the roller portion in a second predetermined cross section perpendicularly intersecting with the rotating axis line of the roller portion is denoted by \u0394r, and a maximum value of the \u0394r in a winding area where the belt member winds is denoted by \u0394rmax, the \u0394r at a middle position of the winding area with respect to a rotational direction of the roller portion is 50% or more of the \u0394rmax, and an area, where the \u0394r is 50% or more of the \u0394rmax occupies 40% or more and 80 % or less of the entire winding area, and wherein the second predetermined cross section passes through a lateral end of the belt member when a lateral center position of the belt member is positioned at a lateral center of the roller portion.
