Abstract:
An image forming apparatus: includes a developing member to be movable between a development position where the developing member contacts an image bearing member and a separated position where the developing member is separated from the image bearing member; and a control portion controls the number of rotations of a drive portion by causing a light source to emit a light beam when a rotating polygon mirror starts to rotate, and detecting the light beam emitted from the light source by a detecting portion, wherein when the rotating polygon mirror starts to rotate, the light beam does not enter an image region of the image bearing member and the light beam is detected outside the image region of the image bearing member by the detecting portion, in a state of the developing member having moved from the separating position to the development position.

Claim (Index 1):
An image forming apparatus comprising:\n a scanning portion including a light source configured to emit a light beam, a rotating polygon mirror configured to reflect the light beam emitted from the light source in order to periodically scan an image bearing member, and a drive portion configured to drive the rotating polygon mirror; a detecting portion configured to detect the light beam emitted from the light source; a developing member configured to be movable between a development position where the developing member contacts the image bearing member and a separated position where the developing member is separated from the image bearing member; and a control portion configured to control emission of the light source, operation of the drive portion of the rotating polygon mirror and movement of the developing member, wherein the control portion controls a number of rotations of the drive portion by causing the light source to emit the light beam when the rotating polygon mirror starts to rotate, and detecting the light beam emitted from the light source by the detecting portion, and when the rotating polygon mirror starts to rotate, the light beam does not enter an image region of the image bearing member and the light beam is detected outside the image region of the image bearing member by the detecting portion, in a state of the developing member having moved from the separating position to the development position.
