Toner
First Claim
1. A toner comprising toner particles which comprise toner base particles having at least a colorant and a binder resin, and an inorganic fine powder, wherein;
- said inorganic fine powder has a primary-particle average particle diameter of from 30 nm to 300 nm, and has particles having at least one of a cubic particle shape, a cube-like particle shape, a rectangular particle shape and a rectangle-like particle shape and having perovskite crystals;
said inorganic fine powder has particles and agglomerates both having particle diameters of 600 nm or more, in a content of 0% to 1% by number; and
said inorganic fine powder is in a liberation percentage of 20% by volume or less with respect to the toner base particles.
