Abstract

PURPOSE:To obtain the titled toner having high compatibility with resin, superior dispersibility and suitability to color development by adding resin, a colorant and metallic salt or ammonium salt of higher fatty acid. CONSTITUTION:Resin with 40-150 deg.C glass transition point such as polystyrene is blended with 0.1-50wt% colorant such as carbon black and 1-15wt% metallic salt or ammonium salt of 10-42C higher fatty acid such as zinc stearate. Thus, a toner assuming the desired color is obtd. without deteriorating the original color tone of the colorant. By carrying out development with this toner, a fine image free from fog is formed.
