An image forming apparatus is provided which includes: an image carrier that carries an image; a transfer roller that includes a gripping member, and transfers the image to the transfer medium; a suction guide portion that includes a suction unit, and suctions and guides the transfer medium transferred the image, vertically upward with a plane transferred the image of the transfer medium being directed vertically downward; and a transfer medium transporting section that includes a suction member and transports the transfer medium while suctioning the transfer medium by the suction member, the transfer medium transporting section being configured such that a position of starting to suction the transfer medium is arranged at a position having a predetermined relationship with respect to a position of releasing the transfer medium from the gripping member and a position at which the image carrier is separated from the transfer medium.

Image forming apparatus and image forming method

A development apparatus includes an anilox roller for supplying liquid developer to a development roller and a supply roller arranged in a developer container and held in contact with the anilox roller to supply the liquid developer to the anilox roller. An AC voltage is applied to the supply roller, and a bias voltage is applied to the development roller. Liquid developer contained in grooves of undulations of an anilox pattern formed on a surface of the anilox roller is applied to the development roller.

There is provided a development system comprising a developer carrier member that carries a developer, a developer supply roller that supplies the developer carrier member with the developer, a developer container that stores the developer, a toner compression roller that contacts with the developer carrier member and presses toner against the developer carrier member, the toner included in the developer and a density sensing unit that senses a density of the toner in the developer in the developer container. A condition for the toner compression roller is changed depending on the density of the toner in the developer in the developer container or depending on a type of a recording medium.

Image forming apparatus and method that changes toner compression roller condition depending on toner density or recording medium type

An image forming apparatus includes a turnable image bearing body for bearing a latent image; a turnable developer bearing body for bearing liquid developer, the developer bearing body and the image bearing body being pressed in contact with each other at a predetermined press-contact position, the developer bearing body being capable of carrying the liquid developer toward the press-contact position by turning, the image forming apparatus performing development of the latent image, which is bore by the image bearing body, with the liquid developer that has been carried toward the press-contact position; and a controller for causing the development of the latent image to start after a predetermined period of time has passed from when the turning speed of the developer bearing body and the image bearing body reached a predetermined turning speed for development at which the development is performed.

Image forming apparatus, image forming system, and image forming method

A developing device includes: a developer bearing body for bearing liquid developer, the liquid developer bore by the developer bearing body being used by the developing device to develop a latent image bore by an image bearing body; a developer supplying member that has depressions in its surface and whose surface is pressed in contact with the developer bearing body for supplying the liquid developer retained in the depressions to the developer bearing body; and a restricting section for restricting the amount of the liquid developer on the developer supplying member, wherein the amount of the liquid developer, which is retained in the depressions and whose amount has been restricted by the restricting section, before being supplied to the developer bearing body is smaller than the volumetric capacity of the depressions that retain the liquid developer.
