摘要： A pressure-applying device includes a swingable unit body, a roller, an opposing member, a pressure-applying unit, and a drive-force transmitting unit. A swinging center of the unit body is set at a position distinct from a rotation center of the drive-force transmitting unit. A direction of action of driving force of the driving unit substantially coincides with a line joining the swinging center and a point at which pressure application force is applied by the pressure-applying unit. A direction of action of the pressure application force is substantially orthogonal to the direction of action of the driving force.

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.
