Abstract (en)
A developer composition is disclosed which is characterized by containing two incompatible resinous materials, one having a polar functional group and a glass transition temperature below 0 DEG C, and the other having a polar functional group capable of interacting with the polar functional group of the one material and a glass transition temperature higher than 40 DEG C. The developer may also contain 20-80% by weight of a fine magnetic powder. Images formed from the developer composition can be fixed to a suitable substrate by the application of only force.
