Abstract
A toner for a two-component developer comprising the toner and carrier particles, the developer being used for an oilless fixing-type image forming apparatus comprising a developer carrier rotatable at a linear speed of 360-1,680 mm/sec, and a developer adjusting member extending in a lateral direction parallel to the rotational axis of the developer carrier and disposed adjacent to the developer carrier to define a gap therebetween of 0.3-1.0 mm, said image forming apparatus being operated so that the amount of the developer conveyed by the developer carrier and passing through the gap per 1 second is 5.0-25.0 g per 1 cm of the lateral width of the gap, the toner comprising a wax dispersed therein and the toner having a coefficient of dynamic friction in the range of 0.18-0.45.
