Zusammenfassung:A dry developer composition suitable for use in the development of an electrostatic charge pattern is described. This developer composition comprises toner particles the average particle diameter whereof is comprised between 3 and 10 microns, and spacing particles the average diameter whereof is under 40 microns and at least twice the average particle diameter of the toner particles, and is characterized in that the part of spacing particles in the overall amount of spacing particles and toner particles is comprised between 1 and 8% by weight.
