Abstract:
1. An image forming apparatus, comprising: a casing provided with an inner space; an opening/closing cover which is mounted on the casing to be openable and closable for opening the inner space to an outside of the image forming apparatus when the opening/closing cover is in an opened state; an exposure device provided with a laser light source which emits laser light, a housing which houses the laser light source therein and includes an opening for passing the laser light therethrough, and a light transmissive member which is disposed in the housing at such a position as to cover the opening of the housing for transmitting the laser light, the exposure device being disposed in the inner space; an image forming unit provided with an image carrier onto which the laser light transmitted through the light transmissive member is irradiated, the image forming unit being mounted to a first position facing the exposure device in the inner space, and being allowed to be mounted and dismounted to and from the inner space when the opening/closing cover is in the opened state; an airflow generator which generates an airflow in the inner space; a cooling air path which guides the airflow between the exposure device and the image forming unit in the inner space; and a partition member which is disposed between the exposure device and the image forming unit, and is configured to change a state thereof between a first state and a second state, the first state being such that the partition member projects toward the image forming unit mounted to the first position from a side of the exposure device, and constitutes part of the cooling air path when the opening/closing cover is in a closed state, the second state being such that the partition member allows the image forming unit to be dismounted from the inner space when the opening/closing cover is in an opened state, wherein the partition member is configured to be disposed at a projecting position at which the partition member projects toward the image forming unit mounted to the first position from the exposure device side when the partition member is in the first state, to be disposed at a spaced position away from the projecting position toward the exposure device side when the partition member is in the second state in, and to block the airflow from flowing toward the light transmissive member when the partition member is in the projecting position.
