<p>PURPOSE:To provide a one-component toner ensuring high transfer efficiency and high resolution. CONSTITUTION:This one-component toner contg. organopolysilane having high positive hole mobility and low electron mobility, magnetic powder and carbon particles acts as a positively chargeable electric conductive toner because of the high positive hole mobility of the organopolysilane, forms an electric conductive path of a magnetic brush at the time of development, injects positive holes from a developing unit into a photosensitive drum 2 and moves to the exposed part of the drum 2 by attraction. This one-component toner acts as an insulating toner to negative bias at the time of transfer because of the low electron mobility of the organopolysilane and it is attracted to a transfer roll 3 by negative bias and transferred to paper P with high transfer efficiency.</p> |
