Abstract: An image forming apparatus includes an image bearing member, an exposure unit, and a main housing. An electrostatic latent image is formed on the image bearing member. The exposure unit includes an optical device that irradiates the image bearing member with light to form the electrostatic latent image, and a housing that defines a storage space in which the optical device is located. The main housing includes a partition wall that divides an inner space of the main housing into a first space in which the image bearing member is located and a second space in which the exposure unit is located. The housing includes a first opening wall having a first opening through which the storage space communicates with the second space. The optical device irradiates the image bearing member with light through the first opening.

Abstract: An optical scanning apparatus includes a reflecting mechanism, a light receiving element and a restricting mechanism. The reflecting mechanism reflects a light beam such that the irradiation point of the light beam moves in a predetermined scanning direction. The light receiving element is arranged in a movement plane defined by the light beam reflected by the reflecting mechanism, and the light receiving element outputs a light reception signal for adjusting the irradiation timing of the light beam in accordance with reception of the light beam reflected by the reflecting mechanism. The restricting mechanism positions the light receiving element relative to the movement plane.
