Abstract
In an image forming apparatus, a support frame configured to support a plurality of cartridges each including a photoconductor is allowed to be pulled out from a casing of the apparatus. A plurality of light-emitting parts configured to expose a corresponding photoconductor to light is arranged in each exposure unit which is movable between an exposure position proximate to the corresponding photoconductor and a retreating position away from the photoconductor. A pair of side plates of the support frame, which extends in a direction perpendicular to a main direction in which the light-emitting parts are arranged, has guide slots formed therein, each of which is configured to guide movement of a corresponding exposure unit between its exposure and retreating positions. Each guide slot includes a positioning portion configured to position the exposure unit in position in a subordinate direction perpendicular to the main direction and to an exposure direction.
