Abstract:
In an image forming apparatus in which light fluxes emitted from at least two light sources are brought close to one another to be allowed to enter the rotating reflector 35 to be allowed to scan the photoreceptor 39, the cylindrical lens presser spring 12 provided on the cylindrical lens supporting member 10 is positioned such that the lens presser spring 12 pushes the cylindrical lens at a position so that the light fluxes enter the cylindrical lens at ranges extending toward both strides from the lens presser spring 12.
