<p>PROBLEM TO BE SOLVED: To provide toner with which images of high definition and high quality can be obtained stably, deposition property of the toner is decreased, maintenance work is made easy and production of unused toner is suppressed. SOLUTION: The toner consists of particles containing binder resin and coloring agent, and the weight average diameter of the particles ranges from 5 to 11μm. The proportion of particles, having the particle diameter as <=1/2 as the weight average diameter in the distribution of particles by number is <=10 pieces %, and the standard deviation in the weight distribution and number distribution of the particles is <=2.7μm.</p> |
