摘要： A recording-material cooling device includes a first belt, a first cooling unit, and a second cooling unit. The first belt is disposed at a first face side of a recording material. The first cooling unit has a first heat absorbing surface to contact the first belt to absorb heat of the recording material. The second cooling unit has a second heat absorbing surface to directly or indirectly contact the recording material to absorb heat of the recording material. The second cooling unit is disposed at a second face side of the recording material. The first and second cooling units are offset from each other in a transport direction of the recording material. Each of the first and second surfaces has a shape in which an inner area protrudes beyond opposed ends in the transport direction. The first and second surfaces overlap each other in a direction crossing the transport direction.

摘要： A belt member is supported by a plurality of rollers and moves in a predetermined moving direction. A detecting unit detects a displacement of the belt member in its width direction. A correcting unit moves a second end of a first roller from among the rollers in either one of a forward direction and a backward direction while fixing its first end based on a result of detecting the displacement of the belt member such that a tilt of a rotating shaft of the first roller is changed to correct a meandering of the belt member. An adjusting unit adjusts a fixing position of the first end.

摘要： A belt member is supported by a plurality of roller members including a first roller member and moves in a predetermined direction of movement. A coupling member is coupled with the first roller member. An abutting member makes contact with the coupling member by changing tilting of a rotational axis of the first roller member and moves the coupling member in a forward direction and a reverse direction to correct meandering of the belt member. Abutting positions of the coupling member with respect to the abutting member when moving the coupling member in the forward direction and in the reverse direction are variable to support respective movement directions.

摘要： A transfer device includes a rotatable image bearer configured to bear a toner image to be transferred to a recording medium, a first rotator, and a second rotator. The second rotator is configured to contact the first rotator via the rotatable image bearer to form a transfer nip in which the recording medium is sandwiched. The second rotator is rotatable with the image bearer. The transfer device satisfies a conditional expression (t1+R)/(t2+R)>0.98, where t1 represents a thickness of a thinnest recording medium, t2 represents a thickness of a thickest recording medium, and R represents a radius of curvature of the transfer nip.
