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 belt running device includes a plurality of rollers, a belt, a guide, a regulating member, and an abutting member. The belt is wound around the plurality of rollers and configured to rotate. The guide is provided at an end of an inner peripheral surface of the belt. The regulating member is provided at an end of at least one roller of the plurality of rollers in the axial direction of the at least one roller and configured to contact the guide and regulate a movement of the belt in the axial direction of the at least one roller. The abutting member is configured to contact an outer peripheral surface of the belt to press the belt inward in a vicinity of a contact start point at which the guide and the regulating member start to contact when the belt runs.
