Toner and manufacturing method thereof

Abstract

The invention relates to a toner and a manufacturing method thereof, provides a toner capable of obtaining storage durability against heat as well as sufficient low temperature fixing ability and its manufacturing method. The toner comprises toner particles containing a cross-linked polymer having two-valent crosslinking group represented by Formula (1), wherein, R1 is a hydrogen atom or a chlorine atom, R2 is a hydrogen atom, a chlorine atom or a methoxy group.

Description

technical field The present invention relates to a toner and a method for producing the same. Background technique In recent years, from the viewpoint of preventing global warming, energy-saving studies have been carried out in various fields, and information equipment such as image forming devices has also introduced configurations that can be used under energy-saving conditions, such as power saving during standby. , conducted research on lowering the fixing temperature in the fixing process, which consumes the most energy. In order to achieve the above-mentioned lowering of the fixing temperature, for example, Patent Document 1 discloses a toner used in an electrophotographic image forming apparatus, which contains a polymer containing a carboxylic acid component and a polyvalent metal compound. and cross-linked resin. According to this toner, since the bonds involved in crosslinking are cracked by heat to lower the melt viscosity of the resin during heating and fixing...

Problems solved by technology

That is, heat-resistant storage and low-temperature fixability are in a trade-off relationship, and it is difficult to achieve both

However, even if the above resins are used, a minimum fixing temperature of about 150°C is required, and it is difficult to say that sufficient low-temperature fixing properties have been obtained.
