Abstract

An optical scanning device (5) includes first and second light source portions (55a, 55c and 55b, 55d) that emit first and second light beams (D1, D3 and D2, D4), and a scanning optical system including a polygon mirror (51), a scanning lens (56a, 56b, 57a, 57b), a plurality of turn-back mirrors (58a to 61a, 58b to 61b). The turn-back mirrors (58a to 61a, 58b to 61b) include a first mirror (58a, 58b) that reflects the first and second light beams (D1, D3 and D2, D4) having passed through the scanning lens (56a, 56b, 57a, 57b), a second mirror (59a, 59b) that directs the first light beam (D1, D3) reflected by the first mirror (58a, 58b) to an image carrying member (1a, 1c), and third and fourth mirrors (60a, 60b and 61a, 61b) that direct the second light beam (D2, D4) reflected by the first mirror (58a, 58b) to an image carrying member (lb, 1d). The second and third mirrors (59a, 59b and 60a, 60b) are disposed, as seen from the main scanning direction, closer to the polygon mirror (51) than the first mirror (58a, 58b), and the fourth mirror (61a, 61b) is disposed, as seen from the main scanning direction, farther from the polygon mirror (51) than the first mirror (58a, 58b).
