Abstract
Provided is a toner, including a toner particle having: a toner base particle containing a binder resin and a colorant; and protrusion derived from a resin fine particle in a surface of the toner base particle, wherein the protrusion is covered with a condensation product of an organosilicon compound represented by the formula (1), and wherein the resin fine particle is in direct contact with the toner base particle. (Ra)n—Si—(Rb)4-n (1)
Claims6
A toner comprising a toner particle, said toner particle comprising:
- a toner base particle containing a binder resin and a colorant;
- resin fine particles;
- and
- a condensation product of an organosilicon compound represented by formula (1)
- (Ra)n—Si—(Rb)4-n (1)
- where Ra independently represents a halogen atom, a hydroxy group, or an alkoxy group, Rb independently represents an alkyl group, an alkenyl group, an acetoxy group, an acyl group, an aryl group, an acryloxyalkyl group, or a methacryloxyalkyl group, and n represents an integer of from 2 to 4, wherein
- said toner particle has protrusions on a surface thereof, said protrusions being formed from said resin fine particles which are in direct contact with said toner base particle, and
- the surfaces of said protrusions being covered with said condensation product.
