Abstract
A toner is provided, which contains a toner particle and a metal titanate particle, wherein, in a number-based particle size distribution of the metal titanate particle on the surface of the toner particle, when D10, D50 and D90 denote the particle diameter at which the cumulative value from the small particle diameter side reaches 10% by number, 50% by number and 90% by number, respectively, the D50 is at least 10 nm and not more than 90 nm, and the particle size distribution index A, which is represented by D90/D10, is at least 2.00 and not more than 10.00, and the value of storage elastic modulus G' at 40° C. in viscoelasticity measurements of the toner is at least 1.0×10Pa and not more than 1.0×10Pa.
