摘要:
An image forming apparatus includes an image carrier; a developing device; a transfer device; and a fixing device. An electrostatic latent image formed on the image carrier is rendered visible as a toner image by depositing the toner by the developing device, and the toner image is transferred by the transfer device and fixed onto a recording medium by the fixing device and output. The apparatus further includes a density fluctuation meter including a rotary position detector, a density fluctuation detector, and a density fluctuation storage; a density fluctuation extractor unit including a first extractor, a second extractor, and a density fluctuation storage; and a control table generator unit including a control table generator and a control table storage, so that based on the control table stored in the control table storage, the voltage to be applied to the developing device is controlled and the toner image is output.

A correction control method includes performing correction control to bring a control value to a target value or a change through a prediction control system that previously applies a predetermined amount of correction and a predetermined timing. The prediction control system is constructed without performing data offset processing for deriving the predetermined amount of correction and the predetermined timing.

In an image forming apparatus, a first controller forms a first image pattern on an image bearer and determines a first image formation condition based on a detection result of density of a toner image. The first controller then controls a toner image forming device based on the first image formation condition. A second controller forms a second image pattern different from the first image pattern on an image bearer and determines a second image formation condition based on a detection result of density of a toner image. The second controller then controls a toner image forming device based on the second image formation condition.

An image forming apparatus includes an image carrier configured to carry an image and a charger to which a direct current voltage overlapped with an AC voltage is applied as a charging bias to charge the image carrier. The charger is positioned in contact or contactlessly with the image carrier. The AC voltage applied to the charger in an adjustment of the AC voltage is not less than twice a charging start voltage Vth at which the image carrier starts to be charged.

A passenger detection system includes a satellite sensor circuit; and a master determination unit. The satellite sensor circuit includes an antenna electrode which is provided in at least one of a seating face or a back face of a seat; and an electric field generation unit which generates an electric field around the antenna electrode, and generates a current signal based on the electric field. The master determination unit includes a current detection unit which detects a variation of the current signal; and a control unit which determines a sitting situation of a passenger by comparing signal data with threshold data, the signal data being related to a current signal which flows based on the electric field which is obtained from the current detection unit and which is generated at the antenna electrode, the threshold data being related to the sitting situation of the passenger. The satellite sensor circuit and the master determination unit are connected via a power supply line and a ground line. The electric field generation unit generates the electric field based on the voltage supplied from the master determination unit to the power supply line, and the electric field generation unit supplies the current signal to the power supply line.

An image forming apparatus includes a plurality of image carriers, an image forming mechanism, a seamless belt-like intermediate transfer body or a transfer material carrier, a detection mechanism, and an optical detecting apparatus. The optical detecting apparatus includes at least a printed board, and a plurality of photodetectors formed of a light-emitting element, a light-receiving element and light-shielding members, which are mounted on the printed board. The optical detecting apparatus is disposed such that it detects a belt surface adjacent to rollers of the intermediate transfer body or the transfer material carrier, and either displacement of a transfer image or image density is detected by a plurality of photodetectors detecting pattern images which are transferred from the plurality of image carriers to the image transfer body or the transfer material carrier.
摘要:
A black developer is conveyed in a first conveyance chamber in a rotation axis direction while agitating with rotation of a first screw member. A black-toner-concentration detecting sensor detects a toner concentration of the black developer by having contact with the black developer conveyed inside the first conveyance chamber. An average of peak amounts of a pressing force on the black developer, which is conveyed inside the first conveyance chamber by the first screw member, with respect to the black toner-concentration detecting sensor is set within a range of 9.8 15 [N/m2] to 9.8 100 [N/m2].

An image recording system includes two image recording apparatuses each capable of recording images independently. A color image recording apparatus is disposed with a bypass transporting path apparatus. A transporting path connecting apparatus is disposed between the front of a monochrome image recording apparatus and the back of the color image recording apparatus. A final processing apparatus that is common to the color and monochrome image recording apparatuses is disposed in the front of the color image recording apparatus. This system includes a process switching portion that switches an image recording process executed by one image recording apparatus to a substitute image recording process of the other image recording apparatus and a switching determining portion that determines whether the switching is executed by the process switching portion, depending on whether a predetermined condition is satisfied.
摘要:
A first developer container having a toner supplying opening is provided in a developing unit. A toner concentration sensor is arranged downstream of the toner supplying opening to detect toner concentration in developer. A supply controlling unit is provided to determine an excess or a shortage in the amount of supplied toner based on image information correspondingly to a detection result by the toner concentration sensor, and to correct the driving amount of a toner supplying unit that has been determined based on the image information correspondingly to the recognized excess or shortage in the amount of supplied toner.
