摘要： A reversely-rotatable roller conveys a sheet having an image formed on its one side at a sheet conveying velocity faster than that of a conveying roller by normal rotation and then, the reversely-rotatable roller conveys the sheet to a re-conveying path by reverse rotation. The sheet conveying velocity of the reversely-rotatable roller when the reversely-rotatable roller reversely rotates is made slower than the sheet conveying velocity when the reversely-rotatable roller normally rotates so that the sheet conveying velocity of the re-conveying roller is substantially equal to or slower than the sheet conveying velocity of the conveying roller.

摘要： An exhaust mechanism for use in an image development apparatus exhausts air from within the apparatus, taking advantage of an air flow generated by the heating of a fixing unit without the need for an air blower. The apparatus includes a transport path for allowing a recording medium, to which a toner image formed on a photoconductive body, is transferred, to pass therethrough, a transfer unit disposed below the photoconductive body for transferring the toner image to the recording medium, the fixing unit having a heater, and a partitioning plate which separates a space formed below the transfer unit from a space that accommodates the photoconductive body, a toner image forming unit, and the fixing unit, and which is provided with an opening for permitting air to flow near the transfer unit. With this arrangement, a ventilation path for exhausting air outwardly from within the apparatus is formed without the need for the air blower, in which a rising air flow is exhausted, passing through the opening in the partitioning plate, near the transfer unit, and through an opening formed in the cabinet of the body of the apparatus.

摘要： A sheet feed roller is urged into contact with the upper surface of a sheet at the top of a stack of sheets supported on a sheet support and an inclined separation plane separates a sheet, fed forward by the sheet feed roller, from the other sheets of the stack of the sheets. A rotatable separation roller is disposed between the inclined separation plane and the sheet feed roller such that the separation roller is urged into contact with the upper surface of the sheet fed forward by the sheet feeding roller. The separation roller is movable depending on the rigidity of the sheet so that when the sheet being fed forward has low rigidity, the sheet is bent starting from a line where the sheet is in contact with the separation roller, but when the sheet being fed forward has high rigidity, the separation roller is moved upward thereby allowing the sheet is bent starting from a line where the sheet is in contact with the sheet feed roller.
