<p>PROBLEM TO BE SOLVED: To provide the toner for developing the electrostatic latent image superior in fluidity in spite of spite of small grain sizes and freed of attachment of a part of the toner components to a photoreceptor at the time of image transfer and void in the solid printed aprts of an original image and also to provide such a toner adapted to forming full color images. SOLUTION: These toners for developing the electrostatic latent image comprise as outer additives fine hydrophobic inorganic particle A having a number average particle diameter of 5-70nm and fine inorganic particle B having a number average particle diameter of 80-800nm and containing particle of >=1000nm in diameter in an amount of <=20 number %, and the toner particle satisfy the following inequality: 1.45-0.05×D50 <=D25 /D75 <=1.75-0.05×D50 in which each of D25 , D50 , and D75 is each particle diameter when each becomes 25 volume %, 50 volume %, and 75 volume % of the total particles at the time of integrating the toner particles from the larger particle diameter side to each volume %, and D50 is in 3-7μm.</p> |
