| titleOfInvention | Two-component developer |
| abstract | (57) [Summary] [Structure] A two-component developer containing a toner and a carrier. The toner contains toner particles, and the toner particles are a fixing resin, And containing magnetic powder in a predetermined ratio. The resin contains styrene and a monomer having an anionic polar group, and contains a low molecular weight copolymer having a styrene composition ratio of 70% or less, and a high molecular weight copolymer. The particles of the carrier have core particles made of a specific magnetic material having concave portions on the surface and a coating layer, and the coating layer is made of a resin composition containing a thermosetting resin and a thermoplastic resin, and the concave portions of the core particles are Fill and cover 0.1 to 60% of the surface area. [Effect] A two-component developer containing no charge control agent is provided. No toner scatter, excellent chargeability and transfer efficiency, and a copy image of required density can be stably obtained for a long time. Further, the poor charging caused by using the low molecular weight styrene having a strong negative charging tendency can be eliminated, the charging of the toner can be stabilized, and the longevity can be achieved. |
