摘要： A developing device, process cartridge, and image forming apparatus, include at least one developing roller. A plurality of transport members with screw and shaft portions, transport developing agent housed within the device in a longitudinal direction, and form a circulation path. A discharge aperture, formed in a transport path wall of one transport member, discharges developing agent to the outside when a surface of the developing agent transported by one of the plurality of transport members exceeds a predetermined height. The one transport member is adjacent to the developing roller that supplies the developing agent and includes, in a part in the longitudinal direction, an area on which the screw portion is not formed. The discharge aperture is disposed opposite to the area on which the screw portion is not formed, and the length of the discharge aperture is formed smaller than that of the area in the longitudinal direction.

摘要： A developing device, process cartridge, and image forming apparatus, have transport members with screw and shaft portions, transporting developer within the device in a longitudinal direction of a circulation path. A supply supplies new carrier to the device. A discharge aperture in a transport path wall of one transport member discharges developer outside the circulation path, when a surface of the developer transported by the one transport member exceeds a predetermined height. A bias path aperture in the transport path wall upstream of the discharge aperture has a bottom at a higher level than a bottom of the discharge aperture, and diverts developer at a level higher than the bottom of the discharge aperture to another transport member. An area in the longitudinal direction of the one transport member has no screw portion, and the discharge aperture is disposed opposite the area and has a length smaller than the area.

摘要： A premixed developing system developing device, process cartridge, and image forming apparatus, in which a developing agent thrown up by a transport member is not discharged from a discharge aperture, variation in the quantity of the developing agent discharged to the outside does not occur, and the image quality of images output is stable. A discharge aperture is formed in the wall of a transport path of a transport member to discharge the developing agent to the outside when the surface of the developing agent exceeds a predetermined level. The transport member is provided with an area, in a part in the longitudinal direction, in which a screw portion is not formed. The discharge aperture is disposed opposite to the area, where the screw portion is not formed on the transport member, and is formed such that the length of the discharge aperture is smaller than the length of the area in the longitudinal direction.

摘要： An image forming apparatus includes a developing unit having a photoreceptor, for making an electrostatic latent image on a surface of the photoreceptor visible as a toner image. A toner hopper stores toner to be supplied to the developing unit and a cleaning device removes and recovers the toner remaining on the surface of the photoreceptor after the toner image has been transferred onto a recording material. A toner transporting passage is connected between the cleaning device and the toner hopper, through which the toner recovered by the cleaning device is returned to the toner hopper. A toner exhausting port is disposed at a part of the toner transporting passage, from which the toner being returned from the cleaning device side is exhausted outside the toner transporting passage. An opening and closing member selectively opens or closes the toner exhausting port, wherein an inner diameter of the toner exhausting port is made larger than that of the toner transporting passage.

摘要： A liquid discharge head includes a head body, a wiring member, a connector, and a protector. The head body discharges liquid. The wiring member transmits a signal to the head body. The connector is disposed at the wiring member to connect the wiring member to the head body. The protector covers the head body and the connector. The head body includes a fitting portion. The protector includes a fitting portion to fit the fitting portion of the head body in a fitting direction. The connector is disposed more backward than a leading end of the fitting portion of the protector in the fitting direction.
