摘要:
An image forming apparatus includes an image carrier that is electrically charged and exposed to light to form a latent image that is developed by liquid developer. A first squeezing roller that is held in contact with the image carrier carrying a developed image bears bias voltage Vs1. A second squeezing roller that is held in contact with the image carrier squeezed by the first squeezing roller bears bias voltage Vs2. The image is transferred to a transfer member that is held in contact with the image carrier squeezed by the second squeezing roller. The absolute values of the bias voltages Vs1 and Vs2 have a relationship of |Vs1|>|Vs2|.
