Abstract: 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.

Abstract: A sheet conveying apparatus includes a guide unit to guide a sheet conveyed by a sheet conveyance portion. The guide unit includes a first movable guide, a second movable guide, and a linking mechanism having an intermediate member through which the first and second movable guides are linked movably with respect to each other. A conveyance regulating portion is supported by the intermediate member and guides the sheet passing through a first conveyance path toward the sheet conveyance portion and guides the sheet that is switched back by the sheet conveyance portion toward a second conveyance path.

Abstract: 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.
