Abstract
In a light guide member included in an image forming apparatus, a transmitting/reflecting portion transmits and reflects light that is emitted from a light source to enter one end of the light guide member in a longitudinal direction and be guided to the other end thereof in the longitudinal direction. The light reflected by the transmitting/reflecting portion is emitted from a first optical surface. The light transmitted through the transmitting/reflecting portion is emitted from a second optical surface. At a cross section orthogonal to the longitudinal direction, a first outer peripheral surface has an arc shape including the first optical surface. Second outer peripheral surfaces expand from both ends of the first outer peripheral surface toward the second optical surface.
