ABSTRACT:
An image forming apparatus having a printing medium feeding unit is provided. The image forming apparatus includes a driving roller and an idle roller which engage with each other and which feed a printing medium, an elastic member which elastically biases the driving roller toward the idle roller, and a releasing member. The releasing member releases the elastic member when a cover door is opened so that the driving roller and idle roller may be separated from one another to remove a jammed printing medium. Accordingly, when a jammed printing medium is removed, the printing medium is not crumpled or torn, parts of the image forming apparatus are not damaged, and the image forming apparatus does not malfunction.
