Liquid developing head liquid developing unit and image forming apparatus |
摘要 |
A liquid developing head is arranged to confront a surface of an image bearing member via a developing gap and a squeeze gap and carries out a developing by use of a developing liquid. The liquid developing head includes a housing, a developing roller, supported by the housing, supplying the developing liquid to the developing gap by rotating so that a portion of the developing roller confronting the image bearing member moves in a direction which is the same as a moving direction of the surface of the image bearing member, a squeeze roller, supported by the housing and arranged on a downstream side of the developing roller in the moving direction of the surface of the image bearing member, removing a surplus developing liquid adhered on the surface of the image bearing member at the squeeze gap by rotating so that a portion of the squeeze roller confronting the image bearing member moves in a direction opposite to the moving direction of the surface of the image bearing member, a developing liquid supply path, formed within the housing and having an ejection hole located at a portion on an upstream side of the developing gap in the moving direction of the surface of the image bearing member, supplied with the developing liquid from outside, and a developing liquid recovery path, formed within the housing, forcibly recovering the surplus developing liquid in response to a suction force applied from the outside.
