Abstract
An electrophotographic developing agent is provided that includes a binder resin, a releasing agent, a colorant, and a charge control agent. By using a binder resin having a high acid value and a mixture of two waxes having different melting points as a releasing agent, a electrophotographic developing agent is obtained, which has excellent fusing property and durability and does not result in hot offset and wrap jamming.
