    摘要: A developing device includes a developer bearer, an end seal, and an inlet seal. The end seal is disposed in contact with a circumferential surface of each end of the developer bearer in a longitudinal direction of the developer bearer. The inlet seal includes a center portion in the longitudinal direction disposed in contact with the developer bearer and each end in the longitudinal direction disposed in contact with the end seal. The end seal includes a cutout portion at a side closer to the center portion in the longitudinal direction and at an upstream side in a direction of rotation of the developer bearer. The inlet seal covers an edge of the cutout portion in the longitudinal direction.

    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.

    摘要: A developing device forms an image by developing an electrostatic latent image on a photoreceptor rotating about a rotation axis. The developing device includes a housing having an opening opposite the photoreceptor, a developing sleeve disposed inside the housing, a magnetic body disposed in a central portion of the developing sleeve and not in no-magnet portions thereof at both sides of the central portion, and seal members supported by the housing. Each of the seal members shields either one of portions of the photoreceptor that are located opposite the no-magnet portions and is in surface contact with either one of end portions of the photoreceptor farther from a center of the photoreceptor than the no-magnet portions. Each of the seal members includes, at an end thereof closer to the center of the photoreceptor than the other end thereof, a non-contact portion that is not in contact with the photoreceptor.

    摘要: A developing device includes a frame, a developing roller, and first and second seals. The frame has a seal adhesion surface and a seal placement portion. The first seal is provided between the frame and a peripheral surface at an end portion of the developing roller. The second seal is in contact with the peripheral surface and has an end region positioned between the first seal and the peripheral surface. The second seal has a first end portion and a second end portion. The first end portion is adhered to the seal adhesion surface and has an end part adhered onto the first seal. The second end portion is in contact with the peripheral surface of the developing roller. The first seal is compressed in the seal placement portion by the second seal to abut on a stepped portion of the seal placement portion.
