  • Patent number: 10394020
    Abstract: An image forming apparatus includes a light scanning device, a light detection unit, and a positional-deviation-amount calculation unit. The light detection unit includes a slit-shaped first light detection region and a slit-shaped second light detection region arranged to have mutually different angles with respect to a scanning direction of the light beam, and outputs a detection signal when the light beam passes through each of the light detection regions. The positional-deviation-amount calculation unit calculates a time period until when the light beam passes through the second light detection region from when the light beam has passed through the first light detection region for each scan of the light beam based on the detection signal output from the light detection unit, and calculates a variation characteristic of a positional deviation amount in a sub-scanning direction of the light beam associated with rotation of the polygon mirror.
