<P>PROBLEM TO BE SOLVED: To obtain an image forming apparatus capable of making printing quality appropriate by making the charging amount of developer to saturated charging amount, recovering the fluidity of the developer and making concentration of the developer uniform. <P>SOLUTION: In the image forming apparatus which has the developing device 100 visualizing an electrostatic latent image being image information on a photoreceptor drum 102 and where the visualized image information is transferred to paper, the transferred information is fixed on the paper by a fixing device 23 and then the paper is ejected, the driving time of the developing device 100 is controlled based on the surface temperature of a fixing roller 231 detected by a temperature sensor 233 and humidity inside the image forming apparatus detected by a humidity sensor 120 when the image forming apparatus is shifted from a stop state to an action state. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
