ABSTRACT:
The present invention provides a toner for electrophotography having a capsule structure including a core and a shell that covers the core, wherein the core contains a colorant, a releasing agent, an amorphous resin, and a block polymer containing a crystalline part and an amorphous part, the weight-average molecular weight of the block polymer is 10,000 or more, the weight-average molecular weight of the resin used in formation of the amorphous part of the block polymer is 1000 to 5000, and the weight-average molecular weight of the resin used in formation of the crystalline part of the block polymer is at least 2 times the weight-average molecular weight of the resin used in formation of the amorphous part of the block polymer, a method of manufacturing the same, a developer for electrophotography including the toner and a carrier, and an image forming method using the developer for electrophotography.
