摘要： A developing device includes a developing roller, a toner supply roller, a casing, a film member, a biasing member, a link member, a link member drive mechanism, and an oscillation mechanism. The film member is disposed on an upper surface of an inner wall portion of the casing, with the biasing member coupled to one longitudinal end of the film member. The link member is coupled to the other longitudinal end of the film member. The link member drive mechanism drives the link member. The link member drive mechanism makes the link member intermittently pull the film member to thereby cause reciprocation of the film member in a longitudinal direction. The oscillation mechanism causes an upper end portion of the film member to oscillate in a direction orthogonal to the upper surface of the inner wall portion along with the reciprocation of the film member.

摘要： A toner carrier includes a metal core, a barrel formed on an outer circumference of the metal core and including at least an elastic layer, and a coating formed on outer circumferences of both ends of the barrel. The coating has a thickness and a width of an outer circumference of the coating is different from a width of an inner circumference of the coating. The width is from an end surface of the barrel along an axis of the barrel, and the width of the outer circumference is larger than the width of the inner circumference so that the end surface of the coating is reversely inclined.
