摘要： A developing device includes a developer bearer, a developer regulator disposed opposite the developer bearer across a first gap, and an opposing member having an opposing face disposed opposing the developer bearer across a second gap wider than the first gap. The opposing face is disposed adjacent to and upstream from the developer regulator in a direction of rotation of the developer bearer. The opposing face is inclined relative to an orthogonal plane direction orthogonal to a side face of the developer regulator. The opposing face is inclined to progressively reduce a distance from the developer bearer to the opposing face in a direction of rotation of the developer bearer. A difference between the second gap and the first gap is not greater than 1.75 times as large as the first gap.

摘要： A powder amount detector includes a vibration plate secured to a powder container to contain powder and positioned at a predetermined position in a stationary state, a shaft to rotate inside the powder container, a contact member attached to the shaft, a vibration detector to detect vibration of the vibration plate, and a detection result processor to determine an amount of the powder in the powder container according to a detection result generated by the vibration detector. The contact member is to flip the vibration plate to cause the vibration plate to repeat elastic deformation and reversion to vibrate. The contact member is to exit an area opposed to the vibration plate after the contact member flips the vibration plate by the time the vibration plate returns to the predetermined position.

摘要： A development device includes a developer container, a developer bearer to carry developer to a development range, a partition dividing at least partly the developer container into a supply compartment and a collecting compartment, with an end portion of the partition facing a circumferential surface of the developer bearer, a developer supply member in the supply compartment to supply the developer to the developer bearer, and a developer collecting member in the collecting compartment above the developer supply member, to receive the developer from the developer bearer. An opening is formed in a downstream end portion of the partition in a developer conveyance direction of the developer collecting member to cause the developer to fall to the supply compartment, and a width of the opening in a direction perpendicular to the axial direction increases toward downstream in the developer conveyance direction of the developer collecting member.

摘要： A developing apparatus contains a developer for developing a latent image formed on an image carrier. The developing apparatus includes a developer carrier disposed opposite to the image carrier; a developer regulating member regulating an amount of the developer carried by the developer carrier; and a developer circulating unit transporting the developer in a circulating path. The developer circulating unit includes a rotatable first transport member supplying the developer to the developer carrier while transporting the developer in a horizontal direction, a shielding member preventing the developer separated from the developer carrier from flowing back toward the first transport member, and a rotatable second transport member collecting the developer separated from the developer carrier while transporting the developer in the horizontal direction. A distance between the second transport member and the developer carrier is greater than a distance between the first transport member and the developer carrier.

摘要： A developing device includes a developer bearer to carry, by rotation, developer to a developing range, a casing including a developer container to contain the developer and housing the developer bearer, a gap retainer adjacent to the developer container and downstream from the developing range in a rotation direction of the developer bearer, an opposing wall opposing an end face of the gap retainer in an axial direction of the developer bearer, a first seal disposed between the end face of the gap retainer and the opposing wall, and a contact portion disposed adjacent to an end portion of the gap retainer in the axial direction of the developer bearer. The gap retainer secures a predetermined gap between the developer bearer and the gap retainer. The contact portion contacts, via a second seal, the gap retainer in a direction intersecting the axial direction of the developer bearer.
