ABSTRACT:
A liquid type developing apparatus includes a developing liquid chamber containing a developing liquid comprised of toner and an organic solution. A recording sheet having an electrostatic latent image on its surface passes between a pair of upper and lower electrically conductive electrode members arranged so that at least one of such members contacts the developing liquid. An electric power source is connected to one of the electrode members for impressing a bias voltage thereto, such one member being arranged in non-contacting relationship with the chamber, and the other of such members being arranged in electrically conductive relationship with the tank, whereby any leakage of the impressed voltage due to attraction of the toner to the members, the tank or to bearings provided for the members, is substantially avoided.
