Abstract
A multi-beam optical scanning device capable of suppressing jitter at the image edges within allowable tolerance by satisfying the following equation: ##EQU1## Where r represents the radius of photosensitive member (mm); .alpha. represents the maximum value of the angle obtained by subtracting the angle formed by the light beam and the scanned line on the surface of the photosensitive member from 90 degrees; D represents the distance (mm) on the surface of the photosensitive member between the light beam condensing position on the furthermost upstream side and the condensing position on the furthermost downstream side in the direction of rotation of the photosensitive member.
