<p>PURPOSE:To provide a toner capable of preventing the generation of a drum filming layer. CONSTITUTION:The toner 110 satisfies the equation, Y<=-0.35X+(67-2D), when the average particle diameter calculated from number distribution by a granuometer using the change of electric resistance in accordance with the volume of the toner particle, which is generated when the toner particle passes through a fine pore of a narrow pore pipe, is expressed by Dmum, the diameter of the fine pore is expressed by Xmum and the frequency of the particle showing the particle diameter of <=5mum is expressed by Y%.</p> |
