According to one embodiment, an image forming apparatus includes a retaining roller, a nipping device, a retaining device, an image forming head, and a controller. The retaining roller retains a recording medium and rotates. The nipping device is capable of operating to open and close and holds the recording medium between the nipping device and the surface of the retaining roller to mechanically retain the recording medium. The retaining device retains the recording medium on the surface of the retaining roller. The controller controls, on the basis of a condition for use of the recording medium, the nipping device to nip the recording medium between the nipping device and the surface of the retaining roller.

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.

According to one embodiment, an image forming apparatus includes a curl forming unit, an endless device, an attracting unit, and an image forming unit. The curl forming unit forms a curl in a recording medium. The endless device holds the recording medium in which the curl is formed by the curl forming unit. The attracting unit applies attraction force for attraction to the surface of the endless device to the recording medium. The image forming unit forms an image on the recording medium held on the surface of the endless device by the attraction force applied by the attracting unit.

A recording head where an actuator, a cavity portion and a flexible flat cable are placed one on another is provided in a head holder of a carriage. A drive IC chip is mounted on the flexible flat cable. A bottom plate portion of a first heat sink is in contact with the drive IC chip so as to be thermally conductable, and a side plate portion thereof is disposed in a standing condition. A base end of a second heat sink is in contact, so as to be thermally conductable, with a wiring pattern formed portion of the flexible flat cable between the drive IC chip and the actuator, and a heat dissipating portion of the second heat sink is extended below the bottom plate portion, and a part of the heat dissipating portion is exposed to the outside of the head holder.

A liquid supply apparatus includes a container mounting portion and a liquid container. The liquid container includes a case configured to store liquid therein, a first movable member positioned in the case, a second movable member positioned on the case, and a retainer configured to retain the second movable member in the first position. The first movable member and the second movable member include a pair of magnetic materials. When the second movable member moves from a first position to a second position, the first movable member is released from a fixed state in which the first movable member is immovably fixed to the case by a magnetic force acting between the pair of magnetic materials.
