An image forming apparatus has a structure which prevents contamination of charging units charging photoconductors. The image forming apparatus includes photoconductor units, charging units charging the photoconductor units, and a fan-motor unit changing the flow of air between the photoconductor units and the charging units to prevent substances of fine particles from flowing into the charging units.

An image forming apparatus includes a developing unit to form a visible image on a printing medium using developer, a fixing device to fix the developer to the printing medium, and a heat plate placed between the developing unit and the fixing device such that heat generated from the fixing device is absorbed by the heat plate, and transmission of heat to the developing unit is restricted.

Image forming apparatus with improved heat transmission

An image forming apparatus and a printing medium feeding unit thereof are disclosed. The image forming apparatus includes a main body, a cassette removably mounted in the main body to load a printing medium therein, and a sensing unit provided in the main body to sense whether the cassette is mounted in the main body and whether the printing medium is in the cassette. The sensing unit includes a first actuator mounted in the main body to sense whether the printing medium is in the cassette, a second actuator mounted in the main body to sense whether the cassette is mounted in the main body, and a sensor having a sensing part to sense operation of the first actuator and the second actuator. Accordingly, the image forming apparatus can sense whether the cassette is properly mounted in the main body and whether the printing medium is in the cassette, with a simple constitution while minimizing the number of sensors.
