摘要

An image recording apparatus has a photo sensitive member and records an image in accordance with an electrophotography process. The image recording apparatus includes a housing, an optical system for emitting a light beam used for the electrophotography process, a stopper member provided in the housing at a predetermined position, and an exchanging unit detachably provided in the housing and having a developer device used for the electrophotography process. The exchanging unit also includes an optical element, a supporting mechanism for movably supporting the optical member, and an elastic member for pressing the optical member onto the stopper member when the exchanging unit is loaded in the housing at a predetermined position. The light beam emitted from the optical system passes through the optical member in the exchanging unit and is projected onto the photo sensitive member.
