<P>PROBLEM TO BE SOLVED: To provide a developing device capable of preventing a sheet member from being cut, when drawing out the sheet member to open an opening part. <P>SOLUTION: A pressing member 81 serving as a regulation means is provided between a returning route 52C of the sheet member 52 and a lower housing 32, in the sheet member 52 for sealing a flow-in opening part 51. The pressing member 81 is constituted, as its form, to press the returning route 52C of the sheet member 52 onto a going route 52B side, and prevents the returning route 52C from floating up out of a going route 52B, to eliminate the generation of warpage. The sheet member 52 is also regulated from moving, by pressing the returning route 52C toward the going route 52B (flow-in side opening part 51)side in the sheet member 52. A developer coming-in clearance is eliminated to prevent the sheet member from being cut, when drawing out the sheet member. <P>COPYRIGHT: (C)2010,JPO&INPIT |
