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 refill developer storage part, a developing roller, a developer conveyance path, a developer receiving port, a conveyance member, and a magnetic member. The developing roller is driven into rotation in the developing housing and carries a toner on a circumferential surface thereof. The toner is conveyed inside the first conveyance path and the second conveyance path of the developing housing in a circulating manner. A first stirring screw is disposed on the first conveyance path and conveys the toner in a first direction. Downstream of the toner refill port, a magnet is arranged. The magnetic member forms a magnetic blush from a top panel of the developing housing towards the first stirring screw. A refill toner flowed-in through the toner refill port is so conveyed as to fall below the magnetic blush whereby the refill toner is favorably stirred with a surrounding toner.

Abstract: An image forming includes an apparatus main body, a photoreceptor drum, a charging apparatus, a developing device, a transfer apparatus, a charging bias applying unit, a developing bias applying unit, a bias adjusting unit, and a print density measurement unit. The bias adjusting unit forms a non-charged area on a circumference surface of the photoreceptor drum and applies a developing bias constituted of a first electric potential to a developing roller to form a first toner image by an electric potential difference between the non-charged area and the developing roller. The charging bias applying unit forms a second toner image by an electric potential difference between the electric potential area and the developing roller. The charging bias applying unit decides a value of a charging bias corresponding to a target electric potential from measurement results of print densities of the first toner image and the second toner image.
