Abstract
A developing device includes toner, a casing accommodating the toner, a developing roller rotatably fixed on the casing, an elastic blade making contact with a circumferential surface of the developing roller, a seal member, and a cutout portion in the seal member. The seal member is arranged to make contact with a circumferential surface of end portions of the developing roller between the developing roller and a wall surface of the casing and to make contact with an end surface of a tip end of the elastic blade. The cutout portion is arranged on the seal member and is cut out at a potion at a side making contact with a side surface of the tip end of the elastic blade in an axial direction of the developing roller and a side located closer to the wall surface of the casing than the elastic blade in a radial direction of the developing roller.
