Abstract: A recording material cooling apparatus includes: a cooling belt that is in contact with a toner-image surface of a recording material on which a toner image is heated by a fixing device to be in a fusing state, to cool the recording material while conveying the recording material; and an air blowing unit that blows air toward the toner-image surface of the recording material which is between the fixing device and the cooling belt, the toner-image surface being in the fusing state, or an air sucking unit that sucks air from the toner-image surface.

Abstract: An aspect of the invention is a recording medium transport device including: a rotating body pair including a pair of rotating bodies disposed on a transport path of a recording medium; a pressing mechanism pressing the rotating bodies in a direction to approach each other; elastically deformable first-large-diameter-portions provided at both axial direction outer-sides of a region where the recording medium passes of at least one of the rotating bodies, the first-large-portions having a larger diameter than the outer diameter at the region; and second-large-diameter-portions provided at both axial direction outer-sides of the region of at least one of the rotating bodies, the second-large-diameter-portions having a larger diameter than the outer diameter at the region and having a smaller diameter than the first-large-diameter-portions, and the second-large-diameter-portions forming a gap between peripheral faces of the rotating bodies at the region in a state where the first-large-diameter-portions are elas
