    Abstract: An ink-jet recording apparatus includes: a conveyor belt; a recording head including a pressurizing chamber that is configured to store ink, a nozzle that is configured to communicate with the pressurizing chamber, a displacement device that is configured to apply pressure to the pressurizing chamber by being deformed by application of voltage, and a driver circuit that is configured to switch the application of the voltage to the displacement device ON/OFF in response to a pulse drive signal input to the driver circuit; and a control unit. In a meniscus-shaking process before a flushing process, the control unit sets a pulse duration of the pulse drive signal to be smaller than a time constant of a circuit unit that includes the driver circuit and the displacement device.

    Abstract: In a housing, an installation surface (44g) of an image forming lens unit (42L) is formed at a higher position by a level difference than an installation surface (44f) of a polygon motor (41), and when viewed from a rotation axis direction of a polygon mirror unit (40), a diameter (r) of a circumscribed circle passing each apex of the polygon mirror unit (40) is larger than an outer diameter (R) of a rotor part (41a) of the polygon motor (41).

    Abstract: An image forming apparatus includes: a recording head that ejects droplets onto a recording medium; an endless belt that conveys the recording medium toward a position where an image is to be formed on the recording medium by the recording head; a support plate that supports the endless belt; and a suction device which is located on an opposite side of the recording head relative to the endless belt and sucks the recording medium together with air to attract the recording medium to a surface of the endless belt. The support plate includes an air inlet and an air vent. The air sucked by the suction device passes through the air inlet from a side of the recording head toward the suction device. The air inside the suction device passes through the air vent from the suction device toward the endless belt.

    Abstract: The inkjet recording apparatus includes a recording head, a cap member, a humidifying part for humidifying interior of the cap member, a cap moving mechanism, a controller, and a storage part. The storage part has stored a non-capping period table in which a number of vibrations of ink level within each nozzle is increased based on a non-capping period of an ink ejection surface, and a capping period table in which the number of vibrations is decreased based on a capping period of the ink ejection surface. In response to respective lengths of the non-capping period and the capping period from an end of ink ejection until a start of next ink ejection, the controller sets the number of vibrations at a start time of next ink ejection by using the non-capping period table and the capping period table.

    Abstract: An inkjet recording apparatus includes an inkjet head, a head base, a conveyance unit, and a rotation mechanism. The inkjet head ejects ink on to a sheet. The inkjet head is fixed to the head base. The conveyance unit faces the inkjet head and conveys the sheet. The rotation mechanism rotates the head base and the conveyance unit around an axis perpendicular to a sheet conveyance surface of the conveyance unit while maintaining a constant relative position of the head base to the conveyance unit.

    Abstract: A light scanning device includes a polygon mirror, a first incidence optical system, a second incidence optical system, a first scanning lens, and a second scanning lens. The polygon mirror includes a deflection surface ensuring entering of the first light beam and the second light beam at an identical timing. Assuming that a reflection point of a light beam on the deflection surface at time point at which the light beam reflected at the deflection surface passes through a position on an optical axis of a scanning lens, the second scanning lens is superimposed on the first scanning lens at different positions in a main-scanning direction and an optical axis direction such that a circle locus is along an offset curved line. The circle locus is a locus of a point corresponding to the reference point by the rotation of the polygon mirror.
