Abstract
An image forming apparatus for forming images on a roll of recording material, comprising a case accommodating the roll of recording material which is drawn out therefrom. A movable member is disposed within the case and is movable in accordance with the decrease of the radius of the roll. A detectable member attached to the movable member and a detecting member provided outside of the case are for detecting that the detectable member has been brought to a predetermined position by the movement of the movable member when the radius of the roll has reached a predetermined value. The movable member has a length permitting the forward end of the member to move away from the outermost surface of the roll when the radius of the roll has reached the predetermined value.
