Image forming apparatus sequentially outputting a sheet having been subjected to image formation processing to a paper output tray

Abstract

An image forming apparatus capable of effectively cooling down a sheet having been subjected to fixing processing while preventing an apparatus from becoming larger in size and a sheet conveyance failure from occurring is provided. The image forming apparatus () includes a sheet conveyance path (), a fixing device (), a conveyance roller (), an upper sheet guide (), a lower sheet guide (), and a cooling fan (). The conveyance roller () is disposed downstream of a heat-treatment portion in the sheet conveyance path and configured so as to convey a sheet passing the heat-treatment portion to the paper output tray. At a position corresponding to the position of the conveyance rollers (), the upper sheet guide () is provided with a ventilation portion () configured so as to make the cooling air from the cooling device () pass through. At a position opposed to the ventilation portion () of the upper sheet guide (), the lower sheet guide () is provided with a ventilation portion () configured so as to make the cooling air from the cooling device () pass through.
