Abstract

The present invention relates to an optical scanning device and an image forming apparatus. In order to suppress jitter, the degree of convergence of a first incident optical system and the degree of convergence of a second incident optical system are both equal to or greater than 0, and the degree of convergence of the second incident optical system is greater than the degree of convergence of the first incident optical system. An angle of incidence, within a sub-scanning section, of a light beam incident on a deflection surface of an optical deflector from the second incident optical system is less than an angle of incidence, within the sub-scanning section, of a light beam incident on the deflection surface of the optical deflector from the first incident optical system.
