    Abstract: A developing device of the present disclosure includes a developing roller, a toner supplying roller, a regulation blade, a casing, a toner receiver support member, a toner receiver member, and a vibration generator. The toner receiver support member is disposed inside the casing so as to face the developing roller or the toner supplying roller between the regulation blade and an image carrier. The toner receiver member is disposed along a longitudinal direction of the toner receiver support member, and has a toner receiving surface that receives toner falling from the developing roller. The vibration generator vibrates the toner receiver member. At each end part of the toner receiving surface in its longitudinal direction, there is formed a thin-walled portion that is thinner in thickness than other parts of the toner receiving surface.

    Abstract: In a developing device, a sheet member is provided via a gap at a second specific position in a specific region between a position on a downstream side in a first rotation direction relative to a first specific position, and a high-magnetic-force position at which an intensity of a magnetic force is the highest in a second region, on the outer circumferential surface of a developer carrying body. The sheet member limits a layer thickness of a two-component developer carried on the developer carrying body rotating in a second rotation direction. The sheet member is able to elastically deform in accordance with application of a pressing force equal to or greater than a tolerable value in the first rotation direction or the second rotation direction.

    Abstract: A developing device includes a housing, a development roller, and a roller gear. The roller gear is disposed at one axial end of the development roller and transmits a rotational drive force to the development roller. The development roller includes a sleeve and a coating layer. The coating layer is formed by dipping the sleeve in a dipping bath with the sleeve directed axially vertically. The development roller is mounted to the housing such that a lower axial end of the development roller at the time of the dipping is an opposite axial end to the one axial end at which the roller gear is disposed.

    Abstract: An image forming apparatus includes a sheet conveyance passage, a photosensitive drum, a transfer unit, a fixing section, a conveyance unit, one or more detection sensors, an airflow generating section, a cooling airflow passage, and a shielding member. The conveyance unit is at an opposite side of the transfer unit from the photosensitive drum with a predetermined clearance from the transfer unit. Each detection sensor is disposed to face the transfer unit in cross section intersecting the axial direction of the photosensitive drum. The sheet detection sensor performs a predetermined detection. The airflow generating section causes a cooling airflow to flow between the transfer unit and the conveyance unit in the axial direction. The cooling airflow passage guides the cooling airflow toward each detection sensor. The shielding member blocks an airflow from a location around the transfer unit toward the cooling airflow passage in a direction intersecting the axial direction.
