Abstract:
An image forming apparatus including: a light source configured to emit a light beam; a rotary polygon mirror including a plurality of reflection surfaces each configured to deflect the light beam emitted by the light source so that the light beam scans a surface of a photosensitive member; a light receiving portion configured to output a light receiving signal by receiving the light beam reflected by each of the plurality of reflection surfaces; a conversion unit configured to convert the light receiving signal to a pulse signal; a measurement unit configured to measure pulse widths of a plurality of pulse signals corresponding to the plurality of reflection surfaces, respectively; and an identification unit configured to identify a rotation phase of the rotary polygon mirror based on a measurement result of the measurement unit and reference values to be compared with the measurement result.

Claim (Index 5):
An image forming apparatus according to  claim 4 , further comprising a calculation unit configured to calculate average values of the count values held by the count value holding units of the number of the reflection surfaces, respectively,\n wherein the identification unit identifies a reflection surface corresponding to the rotation phase identified based on the average values and the reference values.
