摘要:
An image forming device includes a head including a nozzle that discharges an electrically-conductive recording liquid in accordance with a driving signal; an intermediate transfer body on which the recording liquid discharged by the head is applied; a voltage apply unit that applies a voltage between the intermediate transfer body and the head, so as to decompose the electrically-conductive recording liquid by electrolysis; a transfer unit that transfers an image supported on the intermediate transfer body onto a recording material; and a discharging control unit that generates the driving signal that causes the electrically-conductive recording liquid to be discharged from the nozzle. The discharging control unit generates the driving signal so that a position of a meniscus is placed outside the nozzle during a time interval in which the recording liquid temporarily bridges between the head and the intermediate transfer body.

An image forming apparatus includes a fixing unit and a re-heating unit. The fixing unit fixes a toner image on a recording medium by applying heat to the toner image with a first glossiness level. The re-heating unit re-heats the toner image, fixed on the recording medium by the fixing unit, to set a second glossiness level lower than the first glossiness level.

An electron-emitting device has a pair of device electrodes formed on a substrate and an electroconductive film connected to the device electrodes. The electroconductive film has a first gap between the device electrodes and has a carbon film having a second gap at least in the first gap. The substrate is formed by stacking a nitrogen-contained activation suppressing layer and an activation accelerating layer having a nitrogen containing ratio smaller than that of the activation suppressing layer onto a base and has nitrogen containing ratio distribution in the activation suppressing layer in a film thickness direction. The nitrogen containing ratio of the activation suppressing layer at the activation accelerating layer side is smaller than that at the base side.

A corona charger includes a case provided in the vicinity of a device to be charged. The case includes an opening facing the device, a discharge electrode, a first charging region, and a second charging region. The discharge electrode provided inside the case and supplied with a voltage so as to generate a corona discharge charges a surface of the device from the opening by supplying the corona discharge to the surface. The first charging region includes no grid electrode at a position upstream of the opening in a surface moving direction of the device. The second charging region includes a grid electrode to which a predetermined voltage is applied at a position downstream of the opening. The voltage applied to the discharge electrode is an alternating current (AC) voltage superimposed on a direct current (DC) voltage.

A developing unit for transferring toner onto a latent image on an image carrier so as to develop the latent image includes a toner carrier, an electric field generator and a separating force applicator. The toner carrier including a plurality of electrodes disposed along the surface thereof and insulated from each other transports the toner to a developing area facing the image carrier. The electric field generator applies a periodic voltage to the plurality of electrodes of the toner carrier so that an electric field is generated on the toner carrier surface to cause the toner charged to a given polarity and borne on the surface of the toner carrier to hop. The separating force applicator applies a separating force to separate the toner on the toner carrier from the surface thereof outside the developing area. The separating force applicator is disposed separately from the electric field generator.
