Abstract
Official abstract text for this publication.
For at least 80% of toner particles in a toner, along at least 80% of circumferential length of a toner particle cross-section, a shell layer has a thickness of at least 5 nm and satisfies a condition that a ratio of an intensity INc relative to an intensity INs is no greater than 0.2. For at least 80% of the toner particles in the toner, along at least 80% of the circumferential length of the toner particle cross-section, the shell layer has a thickness of at least 5 nm and satisfies a condition that a ratio of an intensity ISc relative to an intensity ISs is no greater than 0.2.
First claim
Opening claim text (preview).
What is claimed is: 1. A toner comprising toner particles, each including: a core; and a shell layer covering a surface of the core, wherein the core contains a binder resin, the binder resin has an amino group or an amine group or an amide group, and a sulfur compound, the shell layer contains a nitrogen-containing thermosetting resin and a sulfur-containing resin, the nitrogen-containing thermosetting resin is a melamine resin, the sulfur-containing resin is a cop…
