Toner for developing electrostatic latent image and manufacturing method thereof

摘要

According to one implementation, a toner includes a toner mother particle and a convex portion on a surface of the toner mother particle. The toner mother particle includes at least a resin (1). The convex portion is formed from a resin particle including at least a resin (2). An average value of a length of a long side of the convex portion is within a range of 0.1 to 0.5 μm. A ratio between a Young's modulus of a non-convex portion of the toner mother particle (ER (1)) and a Young's modulus of a convex portion of the toner mother particle (ER (2)) is a value (ER (1)/ER (2)) within the range of 1.2 to 2.0.
