1. An optical scanning device configured to expose a charged surface of a photosensitive member to form an electrostatic latent image, the optical scanning device comprising:
a light source configured to emit light;
a deflector configured to deflect the light emitted from the light source;
a driving unit configured to rotationally drive the deflector;
a control substrate provided with the driving unit and the deflector and configured to control the driving unit;
a cover member configured to cover the deflector;
a casing on which the control substrate is mounted;
a plurality of first engagement members configured to jointly engage and fix the cover member and the control substrate to the casing such that the cover member is detachably attached; and
a second engagement member configured to fix the control substrate to the casing,
wherein the second engagement member maintains the control substrate fixed to the casing even in a state where engagement by the plurality of the first engagement members is released and the cover member has been removed from the deflector.
