The first coupler is provided at a first position, in the first base member, based on a position at which the imaging performed by the first optical system is performed. The second exposure head includes: second light emitting devices each emitting a second light beam; a second optical system performing imaging of each of the second light beams; a second coupler; and a second base member. The second coupler is provided at a second position, in the second base member, based on a position at which the imaging performed by the second optical system is performed and is fit into the first coupler.

摘要： An image forming device scans and exposes a photoreceptor with a luminous flux by a light scanning device, which includes a polygon mirror that deflects the luminous flux and scans the photoreceptor in a main scanning direction, a correction unit that corrects a scanning position of the luminous flux in the main scanning direction such that the scanning position of the luminous flux coincides with each reference position, and a position deviation detection unit that detects the deviation amount of the scanning position of the luminous flux in a sub scanning direction. The correction unit corrects the scanning position of the luminous flux in the main scanning direction such that a screen line with an aimed screen angle is formed by scanning with the luminous flux whose scanning position in the sub scanning direction has deviated by the deviation amount detected by the position deviation detection unit.

摘要： A method for generating a BD signal and identifying a reflection surface after a polygonal mirror has reached approximately constant rotation speed increases time to start image formation because the step of generating the BD signal is needed. An image forming apparatus identifies a reflection surface on which a light beam is incident by using the period of an FG signal.
