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.
Claims6
An image forming apparatus comprising:
- a movable member that is positionable at a first position and a second position with respect to a main body of the apparatus;
- a belt, which is in either a pressurized state or a pressure-released state;
- a support member that moves from an internal peripheral side to an outer peripheral side to urge said belt so that said belt is in the pressurized state;
- and
- a restriction member that restricts movement of said support member so that said belt is maintained in the pressure-released state,
- wherein, in a case where said restriction member restricts movement of said support member, when said movable member is moved from the first position to the second position by a user, said restriction member releases restriction of movement to move said support member so that said belt is in the pressurized state.
