TL;DR: A carrier for developing electrostatic latent image includes a ferrite core particle which contains MnO and 0.5 to 4 molar percent of CaO, and a resin coating layer formed on the core particle as mentioned in this paper.

TL;DR: In this paper, a toner for developing electrostatic latent images prepared by the following processes comprising; a process (a) of forming particles for toner containing at least a resin and a coloring agent in a wet process, (b) of aggregating the particles, and (c) of the aggregates passing through a minimal gap of 0.5-10 mm under dispersed conditions in air-stream flowing at a high speed to pulverize the aggregate.

TL;DR: In this paper, the authors proposed a method to obtain a title carrier capable of maintaining a stable triboelectrostatic charge and has the rapid rising of the electrification at the same time by constituting said carrier of a carrier core particle, a thermosetting resin layer which contains a ferromagnetic particle for coating the surface of the carrier core particles and an electrostatic charge control agent fixed to the thermoset resin layer.

TL;DR: In this paper, a developer provides a developer for developing electrostatic latent images comprising: a spherical toner whose number average particle size is 2-10 μm and which at least contains a binder resin and a colorant.

TL;DR: In this paper, a carrier coated by a polymer particle layer containing fine magnetic particles around a magnetic core, which may contain an electrical charge controlling agent, and the core may be pre-treated with a coupling reagent; the carrier gives excellent clearness to the copy and durability at repeating use.
