Abstract: A switch back path is connected to a sheet feed path through a branch portion. A plurality of pairs of forward and backward rotating rollers are disposed along the switch back path from the branch portion. A driving portion selectively supplies rotation of a forward rotation direction or of a backward rotation direction to a plurality of pairs of forward and backward rotating rollers. A separation mechanism separates a first pair of forward and backward rotating rollers from each other. A control portion controls operation of the driving portion and the separation mechanism so that a sheet to be fed into the switch back path and a sheet to be fed out of the switch back path pass each other in the switch back path.

Abstract: A transfer mechanism includes: a transfer unit having a transfer belt; and a belt contact and separation assembly for bringing the transfer belt into, and separating it away from, an electrostatic latent image support by shifting the position of the transfer unit. The belt contact and separation assembly includes:a multiple number of transfer unit shifters that abut the transfer unit and shift the position of the transfer unit; a multiple number of linkage members that link with the plural transfer unit shifters, correspondingly; an elastic member for coupling the plural linkage members; and a driver for actuating the transfer unit shifters through the linkage members.

Abstract: An image forming apparatus includes an image forming portion that forms an image on a recording medium, a fixing portion that heats and fixes an image on a recording medium after forming the image, a feed path that conveys a recording medium after heating and fixing by the fixing portion, a first pair of feed rollers composed of two feed rollers provided in the feed path, and a cooling mechanism that sends cooling air to a nip portion of the pair of feed rollers or to the vicinity thereof. The cooling mechanism increases a cooling air volume when a recording medium is held between the first pair of feed rollers in comparison to the time when the recording medium is not held between the first pair of feed rollers.

Abstract: An image forming apparatus includes: an image forming section on a main feed path for performing image formation on a first recording medium to be subjected to single-side printing and on a second recording medium to be subjected to double-side printing; and an output section for delivering these recording media. The apparatus has first to third positions between the apparatus and the output section at each of which a feed path branches off the main feed path. The apparatus further includes: a subsidiary feed path extending from the first position and joining the main feed path at an entrance of the main feed path; a first switchback feed path formed in a place extending from the second position for turning the second recording medium upside down; and a second switchback feed path formed in a place extending from the third position for turning the first recording medium upside down.
