Abstract:
A developing roller which is rotatable while carrying a liquid developer containing toner and a carrier liquid and which contains an electroconductive agent, a squeeze roller provided in contact with the developing roller through at least the carrier liquid, a voltage source capable of generating a potential difference between the developing roller and a squeeze roller, a current detecting sensor for detecting a current passed between the developing roller and the squeeze roller, a controller capable of controlling the voltage source, and a display device capable of outputting information on a lifetime of the developing roller are provided, and the controller outputs the information on the lifetime from the display device on the basis of a detection result by the current detecting sensor (steps S 5  to S 8 ) when a predetermined potential difference is generated between the developing roller and the squeeze roller by the voltage source (steps S 2 , S 4 ).

Claim (Index 3):
An image forming apparatus according to  claim 1 , further comprising a toner concentration detecting means capable of detecting a toner concentration of the liquid developer supplied to said developing roller,\n wherein said controller supplies the liquid developer to between said developing roller and said electroconductive member when said controller causes said voltage applying means to generate the predetermined potential difference and outputs the information on the exchange of said developing roller on the basis of a detection result of said toner concentration detecting means.
