Developing device, image forming apparatus having the same, and image forming method

An image forming apparatus comprising:

• a development roller to which a liquid toner containing toner particles dispersed in carrier liquid is applied by a toner supplying roller;
• a photoreceptor on which a latent image to be developed by the development roller is formed;
• a compaction roller for compacting the toner particles in the liquid toner on the development roller at a position before the development on the photoreceptor;
• and an intermediate transfer member to which a toner image on the photoreceptor is transferred, and further comprising:
• a paper type selecting means for acquiring information of a type of paper;
• a means of controlling the number of rotations of the toner supplying roller according to the information of the type of paper or a means of controlling the voltage to be applied to the toner supplying roller relative to the voltage to be applied to the development roller according to the information of the type of paper;
• and a means of controlling the voltage to be applied to the compaction roller according to the information of the type of paper.
