    Abstract: An image forming apparatus includes: an image forming portion having an image carrying member, a charging device, an exposing device, and a developing device; a developing voltage power supply; a control portion; and an image density sensor. The developing device has a developer carrying member that carries two-component developer and a toner concentration sensor. The control portion senses toner concentration during calibration or during first image formation after calibration for correcting image density based on the sensing result from the image density sensor. If the difference Vtarget−V between the output value V of the toner concentration sensor actually sensed and a target value Vtarget of the toner concentration sensor to be observed when the toner concentration equals a reference concentration is equal to or larger than a predetermined value, the control portion performs calibration again when the amount of toner consumed after calibration reaches a predetermined threshold value.

    Abstract: A developing device of the present disclosure includes a magnetic roller and a developing roller arranged so as to oppose the magnetic roller. Inside the magnetic roller, a regulation pole and a conveyance pole are provided. The regulation pole is turned toward an opposing surface side of an end portion of a regulation blade provided in a developer container. The regulation pole and the conveyance pole are arranged such that in magnetic fields formed by these magnetic poles, a point where no magnetic pole perpendicular to a surface of the magnetic roller is generated is located in a gap between the surface of the magnetic roller and the regulation blade.

    Abstract: In a developing device, a developing coating layer of each of a plurality of developing rollers has been formed by a dipping method in which a developing base body is dipped in a liquid in a state where the developing base body is in a vertical attitude such that a first end of the developing base body faces down and a second end of the developing base body faces up. The plurality of developing rollers are arranged from an upstream side to a downstream side in a rotation direction of an image-carrying member in such a manner that directions faced by the first end and the second end of each of the plurality of developing rollers are alternately reversed.

    Abstract: A toner supply device for supplying toner to a developing device includes a toner container containing toner to be supplied to the developing device and a remaining amount sensor for detecting the remaining amount of toner in the toner container. The toner container includes a cylindrical rotating container having a spiral conveying rib formed on the inner peripheral surface thereof and a paddle provided so as to be slidable on the inner peripheral surface of the rotating container. The remaining amount sensor detects the remaining amount of toner on the upstream side on or before the contact position of the paddle in the toner conveying direction.

    Abstract: An image forming apparatus includes an image carrier, a developing roller, and a control unit. The image carrier has a surface on which an electrostatic latent image is formed. The developing roller is arranged to face the image carrier to form a development nip between the image carrier and the developing roller. The developing roller supplies toner in a two-component developer carried on a surface of the developing roller to the image carrier in the development nip so as to develop the electrostatic latent image. The control unit drivingly controls the image carrier and the developing roller. The control unit discharges the toner in the development nip to the image carrier in a state where the developing roller is stopped, so as to calculate a toner concentration in the two-component developer based on an amount of discharged toner.

    Abstract: A developing device includes a housing, a developer carrier, a conveying member and a surface layer. The conveying member conveys the developer in the first conveying direction and supplies the developer to the developer carrier. The surface layer is arranged on the circumferential surface of the developer carrier and formed on a surface of a predetermined cylindrical base member. The surface layer is formed by an immersion method of immersing the base member in an immersion tank so that an axial direction of the base member extends along a vertical direction. A lower end side of the base member at the time of the immersion is arranged in a downstream side of the housing in the first conveying direction and an upper end side of the base member at the time of the immersion is arranged in an upstream side of the housing in the first conveying direction.
