Abstract

An optical scanning device includes a light source unit, a polygonal mirror, a scanning lens, a casing, and a temperature sensor. The light source unit is configured to emit a laser beam. The polygonal mirror is configured to reflect the emitted laser beam from the light source unit by being rotated about a rotation axis extending in an upper-and-lower direction, whereby a peripheral surface of an image bearing member is scanned in a main scanning direction. The scanning lens is configured to form the laser beam reflected by the polygonal mirror into an image on the peripheral surface of the image bearing member. The casing is configured to house the light source unit, the polygonal mirror, and the scanning lens. The temperature sensor is configured to detect a temperature in the casing. The temperature sensor is configured to detect a temperature of the developing device.
