The present invention relates to toner comprising a binder resin and a colorant, wherein the toner is manufactured by a wet-type granulation method using an organic dispersing agent, an aqueous extract liquid having a surface tension of 50 to 72 mN/m at 25° C., the aqueous extract liquid obtained by mixing 1 part-by-weight toner and 50 parts-by-weight distilled water for 1 hour at 80° C.
摘要:
Radiation made to enter an entire envelope formed of lead or copper, which is included in a radiation detector, results in generating neutrons. Then, the neutrons enter an NaI (Tl) crystal, a CsI crystal, a BiGeO crystal, a BaF.sub.2 crystal, a GSO (Gd.sub.2 SiO.sub.5) crystal or a GdO crystal, forming a scintillator portion of the radiation detector, and as a result, gamma rays are generated due to a neutron capture reaction. The energy of the gamma rays is measured, thereby detecting the nonuniformity of sensitivity of the scintillator portion of the radiation detector.
摘要:
A toner for electrostatic latent image developing comprises a binder resin and a coloring agent. The binder resin is preferably a polyester resin having specified properties. The coloring agent is preferably a C. I. Pigment Blue 15-3, C. I. Pigment Red 122 or C. I. Pigment Yellow 17. The toner is prepared by emulsion dispersion of a colored resin solution, including the binder resin and the coloring agent in a non-water soluble organic solvent, in an aqueous dispersion. Subsequently, the non-water soluble organic solvent and the aqueous dispersion are removed to produce fine toner particles, which are washed, dried and sorted to produce the toner.
