| 摘要 |
The present invention relates to a toner for electrophotography including core-shell particles as a resin binder each including a core portion containing an amorphous resin (A) having a softening point of 105° C. or lower which is obtained by polycondensing a carboxylic acid component containing an alkenyl succinic acid with an alcohol component; and a shell portion containing an amorphous resin (B) obtained by polycondensing an alcohol component containing an aliphatic diol having 2 to 6 carbon atoms with a carboxylic acid component containing a trivalent or higher-valent polycarboxylic acid compound in an amount of 20 mol % or less. The toner for electrophotography according to the present invention is excellent in heat resistant storage property, low-temperature fusing property and durability.
