    摘要： The invention provides a developing device, a process cartridge and an image forming apparatus that allow preventing abrupt variations in toner charge on a developing roller, caused by intrusion, into a nip, of toner accumulated above a regulating member of the developing device. A developing device using a one-component developer includes: a supply roller to which one-component developer is replenished, by natural motion, from a developer storing section. The bottom of the developing device is of a size that allows the supply roller to rotate. The developing device further comprises a filling member for filling a space above the regulating member, in order to prevent the toner located above the regulating member from intruding into a nip formed between the supply roller and a developing roller.

    摘要： A developing device includes a developing roller to rotate in a predetermined direction of rotation and opposed to or in contact with an image bearer to form a development range, a cover to cover the developing roller downstream from the development range in the predetermined direction of rotation, a sheet member cantilevered by the cover to contact the developing roller with a flat face of the sheet member while trailing along the predetermined direction of rotation at a position downstream from the development range. The cover includes a large gap portion to form a first gap in a first predetermined range in the predetermined direction of rotation and a small gap portion disposed adjacent to and downstream from the large gap portion in the predetermined direction of rotation to form a second gap smaller than the first gap in a second predetermined range in the predetermined direction of rotation.

    摘要： A developing device including a developer container configured to store a developer and a developing unit provided below the developer container. The developer container includes a first developer agitation member, and a developer guide member extending along a rotation path of the first developer agitation member, configured to conform to a shape of the rotation path. The developing unit includes a developer bearing member and a restriction member. The developer guide member prevents the developer from being directly supplied to a restriction nip formed between the developer bearing member and the restriction member and guides the developer to the developer bearing member. An edge of the developer guide member is positioned between the restriction nip and a center of rotation of the first developer agitation member.
