Abstract
An exposure unit includes first and second exposure heads. The first exposure head includes: first light emitting devices each emitting a first light beam; a first optical system performing imaging of each of the first light beams; a first coupler; and a first base member. 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.
