A laser beam printer includes a front face. The front face defines an opening for allowing attaching/detaching a paper feed cassette, an opening for allowing attaching/detaching a process unit, and an opening allowing manual paper feed. Accordingly, the laser beam printer has excellent operability since it allows the user to perform any operation from its front side. At the same time, valuable space at the lateral and upper sides of the laser beam printer is available for effective use.
