Claims (8)

  A latent image carrier on which a latent image is formed;
  A latent image forming unit that forms the latent image on the latent image carrier;
  A developer carrying member carrying a developer containing toner and a liquid carrier, a voltage application roller to which a voltage is applied in contact with the developer carried on the developer carrying member, and the developer carrying member A developing section having a cleaner blade for contacting and cleaning the developer carrier;
  An image forming operation for developing the latent image formed on the latent image carrier using the developer to which a voltage having a first polarity is applied by the voltage application roller, and a polarity opposite to the first polarity. Applying a voltage of the second polarity to lower the toner concentration of the developer carried on the developer carrier, and performing a cleaner cleaning operation of scraping the developer having the lowered toner concentration with the cleaner blade A control unit,
An image forming apparatus comprising:   The developer carrier is a developing roller;
  The image forming apparatus according to claim 1, wherein the control unit applies a developing bias to the developing roller during the image forming operation, and applies the same developing bias as the developing bias during the cleaner cleaning operation.   The image forming apparatus according to claim 1, further comprising a toner removing unit that contacts the voltage application roller and removes the toner from the voltage application roller.   A latent image carrier on which a latent image is formed;
  A latent image forming unit that forms the latent image on the latent image carrier;
  A developer carrying member carrying a developer containing toner and a liquid carrier, a voltage application roller to which a voltage is applied in contact with the developer carried on the developer carrying member, and the developer carrying member A developing section having a cleaner blade for contacting and cleaning the developer carrier;
  An image forming operation for developing the latent image formed by the latent image forming unit using the developer in response to an image forming command, and a solid latent image is formed on the latent image carrier by the latent image forming unit. And a controller for performing a blade cleaning operation for cleaning the developer carrying member developed from the latent image carrying member with the cleaner blade after developing with the developer carried on the developer carrying member.
An image forming apparatus comprising: The image forming apparatus according to claim 4, wherein the solid latent image is formed over a time equal to or longer than a rotation period of the developer carrier .   The image forming apparatus according to claim 1, wherein the control unit causes the blade cleaning operation to be executed after the image forming operation is executed.   The image forming apparatus according to claim 1, wherein the control unit causes the blade cleaning operation to be executed after power is turned on.   A step of applying a voltage of a first polarity to a developer containing toner and a liquid carrier carried on the developer carrier;
  Developing the latent image formed on the latent image carrier using the developer to which a voltage of the first polarity is applied;
  Cleaning the developer carrying member that has developed the latent image with a cleaner blade;
  Applying a voltage having a polarity opposite to that of the first polarity to the developer carried on the developer carrier to reduce a toner concentration of the developer;
  Cleaning the developer having a reduced toner concentration with the cleaner blade; and
An image forming method comprising:
