摘要： A composite magnetic developer having a self-friction-chargeability is in the form of fixable magnetic particles having a particle size of 5 to 30 microns and comprising a finely divided magnetic material dispersed in a binder medium which shows an adhesiveness under application of heat and pressure, in which the fixable magnetic particles contain fine particles of a magnetic material embedded in the surface of the fixable magnetic particles in an amount of 1 to 10% by weight based on the fixable magnetic particles and fine particles of a magnetic material adhering to the surface of the fixable magnetic particles without being embedded therein in an amount of 1 to 20% by weight based on the fixable magnetic particles. This developer provides a sharp and clear transfer image having a high density without fogging or edge effects on a transfer sheet having a low electric resistance such as a plain paper. When this developer is used for development of electrostatic latent images, any particular charging operation need not be performed and any carrier need not be used. Even if this developer is used repeatedly for the copying operation, the composition is not substantially changed and good developing characteristics are retained.

摘要： A charged image on a photosensitive layer is developed with a toner containing a releasing agent and a hydroxycarboxylic acid complex salt to form a toner image. The toner image is then transferred to a receptor sheet and fixed to it. The use of a toner containing a specific hydroxycarboxylic acid complex salt brings about a marked advantage of widening a non-offset region to a higher temperature without impairing the antiblocking property, flowability and heat resistance of the toner.
