Abstract The invention relates to a developer for developing electrostatic images. The developer includes magnetic carrier particles at a loading of from 60 to 99 weight percent of the developer. Toner particles are at a loading of 1 to 40 weight percent of the developer. The toner particles include a resin core particle having an outer surface and 0.05 to 5 weight percent a first metal oxide powder is substantially fixed to the outer surface. The toner particles further include 0.05 to 2 weight percent of a second metal oxide powder that is substantially free to transfer between outer surface of the toner particles and an outer surface of the magnetic carrier surface.
