ABSTRACT:
To enable not only releasing pressurization by a pressurization mechanism for pressurizing a belt thereby preventing a deformation therein but also easily and securely releasing the pressurization mechanism held in the pressure release state, thereby facilitating the installation operation of an apparatus. A pressurization mechanism for pressurizing a belt is in a released state prior to the use of the main body of the apparatus. Prior to the initial use of the main body, the pressurization of the pressurizing mechanism for the belt is exerted in linkage with a user operation of placing a recording material in a feed tray.
