摘要： An image forming device includes a transfer unit that transfers a toner image onto a recording medium that has first and second surfaces and is conveyed in a conveyance direction; a main heating unit arranged downstream of the transfer unit in the conveyance direction, and which contacts and heats the recording medium and fixes the toner image onto the recording medium; a reversing unit that reverses front and back of the recording medium having a first toner image fixed onto the first surface; and a preheating unit arranged between the transfer and main heating units in the conveyance direction and that heats the recording medium having a second toner image transferred onto the second surface. The preheating unit heats the recording medium so that a temperature of the first surface is lower than a softening point of a toner before the recording medium is heated by the main heating unit.

摘要： A fixing device includes: a heating section that heats in a non-contact manner a front surface of a recording medium; a feeding section that feeds the recording medium while causing the front surface to be opposed to the heating section; and a maintaining section that, in order to enable the recording medium to be fed by the feeding section while a rear surface that is opposite to the front surface, and that is in an image region where an unfixed-image is formed on the front surface is in a non-contact state, maintains the non-contact state.

摘要： A transportation device includes a first transporter, a second transporter movable between a contact position and a separate position toward and away from the first transporter to hold a to-be-transported object between the second transporter and the first transporter in the contact position, and a transportation unit that transports the to-be-transported object to a nip area where the first transporter and the second transporter hold the to-be-transported object therebetween while the second transporter is located in the separate position. The second transporter moves from the separate position to the contact position to hold the to-be-transported object transported to the nip area by the transportation unit between the second transporter and the first transporter to transport the to-be-transported object.

摘要： A heating device includes a heating unit that heats in a non-contact manner an upper surface of a transport material that is transported; and a blowing unit that blows air against a lower surface of the transport material via multiple blowing holes that open with respect to the lower surface, the multiple blowing holes being disposed so that blowing holes that are closest and adjacent to each other in a transport direction of the transport material are shifted from each other in an intersection direction that intersects the transport direction.

摘要： A transport device includes a transport unit that transports a sheet-like transport material without holding a one-end-side portion of the transport material in a transport direction; and a blowing unit that blows air against a lower surface of the transport material that is transported by the transport unit via multiple blowing holes that open with respect to the lower surface, an arrangement interval of the multiple blowing holes in a direction of intersection with respect to the transport direction being smaller at two end portions than at a central portion of the blowing unit.
