Abstract
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.
