Abstract

PURPOSE:To prevent toner from flowing out of both end parts of an endless moving member by charging the foot of fiber provided to a seal member in a delta-shaped gap part formed between a step part formed at the pressing part of a contact control member and the seal member covering the step part. CONSTITUTION:Seal members 30 which prevent toner from moving in a lateral direction are installed at both lateral end parts of a toner supply roller 24, and the seal members 30 are formed of fur brush bodies and have 'Teflon(R)' fiber 30b implanted in its base clotch 30a. Further, the seal members 30 are brought into contact with both the toner supply roller 24 and a toner layer control blade 26 along and across both and the free tip part of each 'Teflon(R)' fiber 30b is pressed against the surfaces of the toner supply roller 24 and toner layer control blade 26. Consequently, the leaking of toner from the delta-shaped gap part formed at the step part formed at the pressing part between the endless moving member and contact control member can be eliminated.
