<p>PURPOSE:To take out a jammed sheet between fixing rollers without stain of toner and with the little force when the sheet jaming occurs in the fixing device. CONSTITUTION:A driving release gear 3 to be a rotating and driving of the fixing roller 1 is separated from a driving gear 4, constituting the driving system of the device main body via a driving release arm 11. At the same time, the driving releasing gear 3 is engaged with a breaking gear 20. Since the breaking gear 20 produces braking force proportional to the rotational of fixing roller 1, the fixing roller 1 slowly rotates with a little force in the removal of the jammed sheet. Therefore, the jammed sheet is not pulled out quickly from the space of the fixing roller 1, etc., while unfixing a toner picture, as it is and the toner is ' prevented from sticking to the fixing roller 1 when the jammed sheet is removed.</p> |
