摘要： PROBLEM TO BE SOLVED: To provide an electrostatic charge image developing toner superior in low-temperature fixability, OHP transmittance and resistance offsetting property, without having to substantially apply oil in heat roll fixation and capable of forming a fixed image having high glossiness. SOLUTION: With respect to the molecular weight of the THF-soluble component of the electrostatic charge image developing toner by GPC, the proportion of 5×105 or larger in the integral molecular weight distribution is 1 wt.% or lower, that for 3×103 or smaller is 30 wt.% or lower, and the ratio of the proportion of 5×103 or smaller to that of 1×105 W(5×103)/W(1×105)} or larger is 15-50. The molecular weight of the THF-soluble component of the toner by GPC is distributed in the range 1×106 or smaller, the value of the differential molecular weight distribution of the molecular weight 5×103 is 0.55% or lower and that of the molecular weight 1×105 is 0.15% or smaller.

摘要： PROBLEM TO BE SOLVED: To obtain an electrostatic latent image developer having a wide temp. range for fixing, little dependence on environments and extremely long life, and to provide an image forming method to obtain an excellent image by using this developer. SOLUTION: This electrostatic latent image developer consists of a carrier and a toner. The carrier consists of a core and a resin coating layer having dispersion of resin fine particles and a conductive material. The resin fine particles consist of a nitrogen-contg. resin such as malamine resin. The toner contains a binder resin and a coloring agent, and the binder resin contains a THF-insoluble component by 1 to 25wt.%. It is preferable that the binder resin contains a polyester resin by 5 to 30wt.% THF-insoluble component and that the conductive material is a carbon black.

摘要： PROBLEM TO BE SOLVED: To maintain good electrification charge property even for long-term continuous use without changes in the charge due to environmental changes by forming a resin coating layer comprising three kinds of resins consisting of a hardening resin containing a triazine ring, a crosslinking agent which crosslinks with the hardening resin, and a fluorine-contg. org. resin which does nor crosslink. SOLUTION: At least three kinds of resins, winch are a hardening resin containing a triazine ring, a resin which crosslinks with the hardening resin, and a fluororesin which does not crosslink with the hardening resin are used as a coating resin. The resin coating film has such a density gradient that a larger amt. of the fluoroesin is present on the surface of the resin coating film while the amt. of the crosslinkled hardening resin containing the triazing ring increases toward the surface of the core material. As for the hardening resin containing the triazine ring, melamine, guanamine, cyanuric chloride, ammeline can be used, and especially melamine and guanamine are preferably, As for the crosslinking agent, a single polymer or copolymer of monomers containing hydroxyl groups can be used.
