PROBLEM TO BE SOLVED: To provide a laminated structure designed so that when a toner seal material is attached such that the toner seal is curved in a U-shape along a toner supply roller, the surface of the toner seal material in contact with the circumferential face of the toner supply roller is prevented from being wrinkled. SOLUTION: An upper layer 11 disposed in direct contact with the toner supply roller or the like is formed from a fiber material made of nonwoven cloth the frictional coefficient of which is small. A lower layer 13 that requires strength for pivotally supporting the toner supply roller 3 and cushioning ability is formed from foam urethan. An intermediate layer 12 such as a PET film is interposed between the upper and lower layers 11 and 13. COPYRIGHT: (C)2009,JPO&INPIT |
