Abstract
PURPOSE: To prevent whitening, uneven density, or the like on a reversal developed image, by using as a carrier a spherical iron powder having a specified mean particle diameter and volume resistivity, and a toner containing a triaminotriphenylmethane type dye as a charge controller.
CONSTITUTION: A spherical iron powder used as a carrier has a volume resistivitity of 1×107W1×1011Ω.cm and a particle diameter of 80W180μm. A toner consists of 100pts.wt. resin, 3W20wt.pts. carbon black, and 1W20pts.wt. triaminotriphenylmethane type dye, and has 5W20μm means particle diameter. A developer used consists of 100pts.wt. said carrier and 0.5W3pts.wt. said toner has a charge quantity ≤μC/g, preferably 5W25μC/g by a specified measuring method. As a result, a superior reversal image having sufficient image density and prevented from carrier separation or the like.
