  • Patent number: 12153375
    Abstract: An image forming apparatus includes a sheet discharge unit having a rotary unit disposed downstream of a fixing nip in a sheet conveyance direction and discharging the sheet to outside of the image forming apparatus. The rotary unit includes bodies to abut the sheet which are disposed side by side in a width direction orthogonal to the sheet conveyance direction. A stacking unit stacks the sheet discharged by the sheet discharge unit, a fan blows air and includes a rotation shaft extending in the width direction, and a duct discharges the air toward the stacking unit. The rotary unit is disposed such that at least a part of the rotary unit enters an inside of the duct, and with respect to the width direction, at least a part of a first area in which the fan is disposed overlaps a second area in which the rotary unit is disposed.
