ABSTRACT:
An image forming apparatus that can be charged with a sheet cassette with a resealable flexible cover includes a roller member engageable with and translatable across the cover to wind the cover on the roller member. The size of the sheet material accommodated in the sheet cassette can be determined from a bar code and the movement of the roller member can be adjusted in accordance with the size of the sheet material. Timers can be set to provide predetermined time periods relative to the translating opening and closing movement of the roller member and, if these time periods expire, an indicator can be provided to the operator.
