Abstract: A sheet conveyance apparatus includes first and second conveyance paths that eventually merge together. A guide member pair constituting the first conveyance path includes a second path guide member disposed on the second conveyance path side among the guide member pair and having a straight portion and a curved portion provided continuously downstream of the straight portion. A downstream end portion of the guide member is positioned in a merging portion of the first and second conveyance paths. The straight portion includes a plurality of ribs and a slope portion formed thereon. The plurality of ribs project perpendicularly from a base portion and are parallel to the sheet conveyance direction. The slope portion is provided between two of the plurality of ribs adjacent to each other and is inclined from the base portion toward the ridges of the plurality of ribs.

Abstract: In a conveyance operation, a leading edge of a sheet in a sheet conveyance direction is abutted against a second conveyance member in a stopped state while a first drive source is driving a first conveyance member at the first speed, and then a second drive source starts to drive the second conveyance member with a target of a second speed while the first drive source is continuously driving the first conveyance member. A speed change processing is executed during the conveyance operation, such that the first drive source changes the first conveyance member from the first speed to a third speed that is smaller than the second speed before the second conveyance member reaches the second speed, and then changes the first conveyance member from the third speed to the second speed.

Abstract: A guide path branched downward from a conveyance path for guiding a sheet having a toner image fixed thereon to a sheet discharge tray, a switchback path, and a inversed discharge path guide the sheet once, and then guide the sheet to the sheet discharge tray with its front and back surfaces and its leading and trailing edges in a sheet conveyance direction reversed. A fan supplies air between a sheet discharged by a sheet discharge roller and a sheet already discharged onto the sheet discharge tray from a supply opening provided below the sheet discharge roller. A control portion for controlling a blowing operation of the fan selectively operates the fan when discharging the sheet after passing the sheet through the guide path, the switchback path, and the inversed discharge path.
