An image forming apparatus comprises a light-emission unit, a reflecting member, a light-receiving unit, a detection unit, a ventilation unit configured to send air to the reflecting member, and a control unit. The control unit adjusts at least one of an operation duration and an airflow rate of the ventilation unit, in accordance with a detection signal outputted by the light-receiving unit when a sheet is not at a position where light crosses a conveyance path.

A toner image is formed on a first sheet surface and then heated. A conveyance unit includes a first rotary member configured to contact the first sheet surface and a second rotary member configured to contact a second sheet surface opposite to the first sheet surface. A conveyance guide is provided with an opening through which air is blown to the first sheet surface. The conveyance guide includes a first surface part and a second surface part. The first surface part is disposed on a location in a width direction overlapping with a location in the width direction of the first rotary member. In at least a part of a range between the opening and the first rotary member in the sheet conveyance direction, the first surface part is protruded with respect to the second surface part in a height direction.

The sheet feeding apparatus includes a sheet tray on which sheets are stacked, a feeding roller which contacts a top sheet on the sheet tray and feeds the sheet in a sheet feeding direction, and a pair of intermediate conveying rollers which receives the fed sheet and conveys the sheet in a sheet conveying direction. The sheet feeding apparatus further includes a fixed slope portion, a sheet separation member, and an opposite member. The fixed slope portion includes a separation slope which is inclined in downstream of the sheet feeding direction as it is closer to the pair of intermediate conveying rollers, so as to abut against the sheet fed by the feeding roller and separate the sheet one by one. The sheet separation member and the opposite member have a separation nip portion which separates the sheet having passed through the separation slope one by one.
