Abstract
A toner seal member which is maintainable in contact with a rotating member to seal a toner. The toner seal member has a non-woven fabric sheet on a support layer formed of an elastic member, and the non-woven fabric sheet has a fiber diameter of from 2 μm to 10 μm. This toner seal member can prevent fine toner from leaking via a photosensitive drum surface and can also prevent coarse powder toner from adhering to the photosensitive drum surface, and has sufficient toner sealing properties without damaging the functions of the photosensitive drum and image-forming performance.
