摘要： According to one embodiment, an inkjet head has a pressure chamber for storing an ink, an actuator for changing the volume of the pressure chamber, and a nozzle through which the ink stored in the pressure chamber is ejected when the volume of the pressure chamber is changed. Additionally, the inkjet head has a temperature sensor for detecting the temperature of the ink and a controller for controlling the actuator by outputting an ejecting waveform. The ejecting waveform sequentially includes an expansion pulse, a first contraction pulse, and a second contraction pulse. The controller changes the pulse width or voltage value of the second contraction pulse when the temperature detected by the temperature sensor changes.

摘要： According to one embodiment, an image forming apparatus includes a conveying mechanism, a printing head, a charging device, a humidity sensor, and a controller. The conveying mechanism conveys a recording medium by adsorbing the medium using an electrostatic force. The printing head forms an image on the recording medium which is conveyed by the conveying mechanism. The charging device performs charging according to applied voltage, and adsorbs the recording medium using the electrostatic force, to the conveying mechanism. The humidity sensor detects the humidity in the apparatus. The controller determines voltage to be applied to the charging device in order to charge the charging device, on the basis of at least the humidity which is detected by the humidity sensor.

摘要： According to one embodiment, an inkjet recording apparatus includes a retaining roller, a charging member, an inkjet head, a reversing device, and a controller. The retaining roller retains a recording medium on the surface thereof and rotates. The charging member is arranged to be opposed to the surface of the retaining roller and attracts the recording medium to the surface of the retaining roller with electrostatic force and retains the recording medium on the surface of the retaining roller. The controller controls a position in an approaching and separating direction of the charging member with respect to the retaining roller if the recording medium is reversed by the reversing device after image formation on a first surface of the recording medium and then electrostatically attracted with a second surface of the recording medium faced to the outer side.
