Abstract:
An electrostatic latent image developing toner has an average sphericity of at least 0.94 but no more than 0.98, the particles for which the accumulated equivalent spherical diameter on a number basis is at least 90% and the sphericity is less than 0.92 account for less than 3% of the entire toner, the proportion of particles having a sphericity of at least 0.90 but less than 0.95 is at least 20% but no more than 40% of the entire toner, and a proportion of particles having a sphericity of at least 0.95 but no more than 1.00 is at least 60% but no more than 80% of the entire toner.
