A cartridge type HDD unitis mounted on the outside of a back plate panelof an exterior cover rear portion in an image forming apparatus. An HDD main body is detachably attachable into a unit case. When the HDD main body is attached into the unit case, the HDD main body is substantially horizontally inserted from a sideways case opening. In the conventional art, there is the problem that the HDD main body is caused to fall carelessly in attachment working in which the HDD main body is mounted to a housing case such that the HDD main body drops into a housing case in a vertical direction. However the problem above described is eliminated, and the attachment working of the HDD main body can be performed easily and safely. With reference to security protection of information stored in the on-board mounted built-in HDD, the information stored in the built-in HDD can be transferred to and stored in the cartridge type HDD.
