PROBLEM TO BE SOLVED: To provide a developer which does not increase fogging even with an image forming device using roller materials not emitting oligomers and obviates the occurrence of the phenomenon of filming of toners to an electrostatic latent image carrying member and developing rollers. SOLUTION: Silicone oil or fluorine oil is added to the toners 106. The amount of the oil to be added is confined to 0.01 to 3.0 wt.%, by which the prevention of the filming on the electrostatic latent image carrying member 101 and the developing roller 105 is made possible in spite of the use of the roller materials having an easy tendency to the occurrence of the filming and the widening of the selection width of the materials of the respective rollers is made possible. Since the increase of the fogging in continuous recording and the degradation in recording density may be prevented as well, the recording quality after continuous recording is improved. |
