WET TYPE DEVELOPING APPARATUS AND WET TYPE DEVELOPING METHOD

摘要

A wet type developing apparatus is provided which allows printing in a quality that is stable at an increased printing speed and also with changes in physical property of a liquid developer. The wet type developing apparatus to this end includes a liquid developer feed pathway which comprises a developing roller 7 for feeding the liquid developer onto a photoconductor drum 3; an anilox roller 9 immersed in part in the liquid developer and driven to rotate in rotational contact with the developing roller; and a doctor blade 11 disposed in contact with a surface of the anilox roller for controlling the rate of drawing up of the liquid developer. The developing and anilox rollers have their peripheral surfaces moving in an identical direction and at an identical rate of movement in an area of their rotational contact. A toner charger 12 is disposed opposite to a surface of the anilox roller downstream of an area of contact of the doctor blade with the anilox roller and upstream of an area of rotational contact of the anilox roller with the developing roller in a rotation direction of the anilox roller.
