A multi-beam deflector and a multi-laser scanning unit including the same are provided. The multi-beam deflector deflects N incident light beams which are spaced apart from each other by a beam pitch. The N incident light beams are deflected onto N photoreceptors which are spaced apart from each other. The beam deflector includes a deflecting reflection mirror that includes N deflecting reflection surfaces and a driving body. The N deflecting reflection surfaces correspond to the photoreceptors with a predetermined angle between each of the reflection surfaces, and respectively scan the N incident light beams to the corresponding photoreceptors. The driving body vibrates the deflecting reflection mirror about a rotation axis. The number of optical components is reduced and the apparatus is simpler, alignment of the optical components is simpler, and the degree of freedom of optical components is improved.
