In a sheet delivery/guide apparatus, a sheet released from a convey device and falling piles on a first pile device. A first blowing device is arranged above the first pile device and blows toward the first pile device. An air controller selectively performs switching between an air supply state and an air supply stop state of the first blowing device for the sheet. A guide member is supported movably and guides the sheet that passes the first pile device while being held by the convey device. A guide member switching unit switches the guide member between a guide position to enter a sheet falling path, extending from the convey device to the first pile device, to guide the sheet, and a retreat position to retreat from the sheet falling path. A controller controls the air controller and the guide member switching unit on the basis of a convey speed of the convey device. Thus, in a first mode in which the sheet piles on the first pile device, the air supply state of the first blowing device for the sheet is effected and the guide member is positioned at the retreat position. In a second mode in which the sheet passes the first pile device and is conveyed downstream in a sheet convey direction, the air supply stop state of the first blowing device for the sheet is effected and the guide member is positioned at the guide position.
