ABSTRACT:
A one-component high-resistance toner is transferred from a rotatable sleeve, or first transport member, to an endless belt, or second transport member. An electric field having a predetermined intensity is developed between the sleeve and the belt in a direction for transferring the toner from the former to the latter. Toner particles charged to a polarity opposite to a desired polarity are prevented from moving from the sleeve toward the belt.
