摘要： In one example in accordance with the present disclosure, a developer unit seal is described. The developer unit seal includes an endcap. The endcap has an opening to receive a dynamic seal for a roller, an inlet to receive print fluid, and a channel embedded in a surface of the endcap. The channel connects the inlet with the opening to direct print fluid to the opening. The developer unit seal also includes a sealing member to cover the channel.

摘要： A seal member includes a seal surface that comes into contact with and slides with an end portion of an outer circumferential surface of a developing roller. The seal surface includes a first seal region configured of a plurality of first fiber bundles including a first fiber having a charge property that repels a developer, and a second seal region configured of a plurality of second fiber bundles including a second fiber having a charge property that attracts the developer, both extending in an inclined direction such that a portion thereof closer to an opening portion of a frame body of a developing unit is located further downstream in a rotating direction of the developing roller, and being alternately disposed in the rotating direction, and a proportion of a portion occupied by the second fiber bundles on the seal surface is at least 5% and not more than 60%.

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： In a developing device, a developing roller has a circumferential surface and an axial end portion. A thickness-regulating blade includes a pressing part protruding to contact the circumferential surface. A first sealing member is provided between a housing and the axial end portion, and includes a first layer; and a second layer. The first layer has a first layer surface disposed to contact the circumferential surface. The second layer supports the first layer and has a protruding part protruding inward of the first layer in an axial direction of the developing roller and having a second layer surface opposing the circumferential surface. The housing has a wall part disposed between the pressing part and the protruding part in the rotating direction of the developing roller. The wall part has an opposing surface opposing the circumferential surface. A lubricant is applied to the first layer surface and the second layer surface.
