An image forming apparatus includes an image bearing member to form a toner image on a recording material with a liquid developer containing a toner and a carrier liquid, wherein the carrier liquid contains a first substance, charged to an opposite polarity to a charge polarity of the toner, for imparting an electrical polarity to the toner, and a second substance, higher in volume resistivity than the first substance, a cleaning portion to collect the liquid developer remaining on the image bearing member after the toner image is transferred onto the recording material, a toner separating device to separate the collected liquid developer into the toner and the carrier liquid, and a carrier separating device to separate the carrier liquid into the carrier liquid containing the first substance and the carrier liquid containing the second substance by applying an electric field to the carrier liquid.
