Abstract
An color image forming apparatus is disclosed which forms an electrostatic latent image on a photosensitive drum with the use of a charger and laser beam for light exposure, develops the electrostatic latent image into a visible image by a developing unit with the use of a liquid developer with a coloring material of very fine particles mixed in an insulating solvent and transfers the visible image to a recording sheet with the use of a transfer roller with a heater reincorporated therein. In this color image forming apparatus, a partition wall is provided for covering the transfer roller as a solvent vapor producing source to prevent the diffusion of a solvent vapor, and a cooling panel constituting at least part of a surface of the partition wall opposite to the transfer roller is cooled to a temperature lower than an ambient temperature within the partition wall, whereby it is possible to suppress the diffusion of the solvent in the liquid developer to a minimal possible level and efficiently collect the solvent for recovery and to achieve a stable developing characteristic.
