Carbon powder used for magnetic jumping type developing and preparation method thereof

The invention discloses carbon powder used for magnetic jumping type developing and a preparation method thereof. The carbon powder used for the magnetic jumping type developing comprises the following raw materials in parts by weight: 70-85 parts of styrene, 15-35 parts of butyl acrylate, 2-10 parts of rosin modified epoxy resin, 2-8 parts of hydrophobically modified pigment, 5-10 parts of wax, 0.1-2 parts of a charge control agent, 1-5 parts of an initiator, 5-10 parts of a surface active agent, 10-30 parts of a coagulant, 5-15 parts of ethanol, 1-5 parts of hydrophobically modified silicondioxide and 1000-2000 parts of water. The carbon powder used for the magnetic jumping type developing is prepared by adopting a miniemulsion polymerization method, and resin is adopted for packaging the pigment, the wax and the charge control agent, so that the uniform dispersion problem of the pigment, the wax and the charge control agent in the resin is solved and the problems that the pigment and the wax are not firmly
