PROBLEM TO BE SOLVED: To improve the sealing property and reduce an amount of generated slide friction heat in a sealing structure allowing a cylindrical rotary body to slide freely on a sealing member. SOLUTION: The sealing structure 1 for preventing a leakage of toner T in a toner storage space 4 of a toner storage vessel (casing) 11 from both end parts in the axial direction of a developing roller 2 is constituted as follows. The sealing member 3 is bonded on a bonding face 13 opposing to outer peripheral faces in both end parts in the axial direction of the developing roller 2 among bottom faces 12 of the casing using adhesive 14. The bonding face 13 is an inclined face composed of a single plane, and an inner side (toner storage side) in the axial direction is formed to be higher than an end face 2a side of the developing roller. A plastic sheetlike sealing member having uniform wall thickness is used as the sealing member 3. The sealing member is pressed against the bonding face 13 on the outer peripheral face of the developing roller and is compression-deformed to constitute the sealing structure. |
