<p>PROBLEM TO BE SOLVED: To much more surely prevent the occurrence of the offset of toner used in an image forming device equipped with a fixing device performing heat-fixing, and also to prevent transfer material from adhering to the fixing device. SOLUTION: As for the toner, the average particle size of the equivalent particle size of synchronous toner that an additive (SiO2 ) adheres to the base particle (C) of resin is set to be larger than the average particle size of the equivalent particle size of the entire toner. Thus, the additive (SiO2 ) is made to evenly adhere at least to the base particle (C) having the larger particle size. Therefore, the base particle (C) having the large particle size largely influences adhesion obtained between the toner and the heating member of the fixing device. Since the adhesion between the toner T and the heating member is reduced by making the additive (SiO2 ) adhere to the base particle (C) having the large particle size in such a way, the occurrence of the offset that the toner adheres to the heating member is restrained. Therefore, the winding of transfer paper round the heating member is effectively reduced.</p> |
