Abstract: The inkjet recording apparatus includes a conveyance belt, a conveyance plate, a suction unit, an inkjet head, and a cleaning unit. The conveyance belt has a plurality of through holes. The conveyance plate includes a plurality of through holes formed in bottom portions of the plurality of recessed portions. The suction unit is configured to suck the sheet to the conveyance belt. The inkjet head includes a head main body and a head end portion adjacent to the head main body, and faces an upper surface of the conveyance plate via the conveyance belt. The cleaning unit removes ink adhering to a lower surface of the head main body. A depth of the recessed portion in a facing region facing the head end portion of the conveyance plate is shallower than a depth of the recessed portion in a region other than the facing region.

Abstract: An inkjet recording apparatus includes a recording head, a wiper member, a cleaning liquid supply device, a cleaning liquid flow path, and a controller. The cleaning liquid flow path includes a vertical tubular member connected to the cleaning liquid supply device and extending upward, and a horizontal tubular member connected to an upper end of the vertical tubular member and extending in a horizontal direction. The controller extrudes a cleaning liquid in at least a part of the cleaning liquid flow path from a cleaning liquid supply port before control of a cleaning operation for wiping an ink ejection surface of the recording head, thereby performing control of an air bubble release operation of the cleaning liquid flow path.

Abstract: A developing device supplies a developer to a photosensitive drum, which has a cylindrical shape, and is rotatable around an axis thereof for forming an electrostatic latent image on the circumferential surface thereof. The developing device is provided with a developing roller. The developing roller is disposed to face the photosensitive drum, and has a cylindrical shape. The developing roller is rotatable around an axis thereof for carrying a developer on the circumferential surface thereof. The developing roller is provided with a small diameter portion. The small diameter portion is a part of the circumferential surface of the developing roller. The small diameter portion extends from an axial end of the developing roller axially inward by a predetermined length, and has an outer diameter smaller than an axially middle portion of the developing roller.

Abstract: In the case of a standard sized sheet, a first controller sets a linear velocity D of an image bearing member at a first velocity and sets a linear velocity S of a toner bearing member so that S/D, which is a ratio of the linear velocity S to the linear velocity D, has a first value and a second controller sets the thickness of the toner layer carried on the toner bearing member at a first layer thickness. In the case of a long sheet, the first controller sets the linear velocity D at a second velocity slower than the first velocity and sets the linear velocity S so that the S/D has a second value larger than the first value and the second controller sets the thickness of the toner layer at a second layer thickness smaller than the first layer thickness.
