<P>PROBLEM TO BE SOLVED: To provide a developing device capable of suppressing rising of temperature. <P>SOLUTION: The developing device includes; a developing roller 11 supplying developer to a photoreceptor drum 4 for developing an electrostatic latent image formed on a surface of the photoreceptor 4, a magnetic roller 12 on whose surface a magnetic brush is formed for supplying the developer to the developing roller 11, a recovery roller 20 for recovering the developer from the developing roller 11, and a cooling means for cooling the developer by cooling the inside of the recovery roller 20. The cooling means has a hollow part 24 formed in the recovery roller 20 with air or coolant circulating in it and a fan 22 for making the air or the coolant flow in the hollow part 24. <P>COPYRIGHT: (C)2009,JPO&INPIT |
