    Abstract: In an exposure device, a light source device having multiple light emitting devices arranged in one-dimensional or two-dimensional directions projects light against an image bearing member. A light source holding member holds the light source device in place. An optical device condenses the light projected from the light source device onto the image bearing member. An optical device holding member holds the optical device to maintain a predetermined gap between the optical device and the light source device on the light source holding member. A positioning member supports the light source holding member above the image bearing member to maintain a predetermined gap between the image bearing member and the light source device on the light source holding member. When seen from a light emitting point of the light source device, a position at which the positioning member supports the light source holding member is opposite the image bearing member.

    Abstract: A light-amount detecting device includes: a light source which emits a light beam; a branching optical element which divides the light beam emitted from the light source into a first light beam traveling in a predetermined direction and a second light beam traveling in a direction different to the predetermined direction; a light-condensing element which condenses the second light beam; a light-receiving element having a light-receiving surface which receives the second light beam condensed by the light-condensing element; and a detector which detects a light-amount of the second light beam received by the light-receiving element, and at least one of a direction of reflected light of the second light beam reflected from the light-receiving surface of the light-receiving element and spread of the reflected light of the second light beam reflected from the light-receiving surface of the light-receiving element is adjusted to control a light-amount of the reflected light of the second light beam returning to the light source.
