摘要： An image forming apparatus and a method of sensing a printing medium jam in the image forming apparatus. The image forming apparatus includes a developing unit, a transfer unit, a fixing unit, a feed-out unit, a lower cover to come in contact with a printing medium when the printing medium is jammed on a feed path and which opens upwards when a pressure of the printing medium caused by the printing medium jam is greater than a predetermined reference value, an upper cover to be opened by the contact of the lower cover when the lower cover opens, and a printing medium jam detection unit operated by the upper cover.
