Title: Toner and image forming device using the same
Inventor: ICHIKAWA KAZUHIRO
IPC: G03G9/08
Filed: 2002-01-23
Abstract: PROBLEM TO BE SOLVED: To reduce the occurrence of the offset of toner used in an image forming device equipped with a fixing device performing thermal fixing, and also to prevent transfer material from adhering to the fixing device. SOLUTION: The toner T is constituted so that the inclination (particle size of additive/particle size of base particle) θ of an approximate line αobtained by making the distribution of the particle size of an additive (SiO2 ) to the particle size of base particle (C) approximate by a method of least square is >=0.4. Thus, the particle size including the primary particle size and the secondary particle size of the additive having low stickiness adhering to the base particle having high stickiness to the fixing device performing the thermal fixing becomes large. Since the sticking force by which the transfer material and the fixing device adhere to each other becomes weak, the offset of the toner to the fixing device is restrained and the adhesion of the transfer material to the fixing device is reduced.
