    摘要： A toner for developing an electrostatic image, comprises a binder resin and a colorant. The toner has a glass transition temperature (Tg) of 65.degree. C. or lower. The binder resin comprises a styrene-acrylic copolymer formed from at least a styrenic monomer and a mixture of two or more acrylic monomers. The binder resin contains 10% by weight or more of THF insolubles. The amount of the styrenic monomer remaining in the toner is 0.005 part or less by weight based on 100 parts by weight of the binder resin component in the toner (50 ppm), and the amount of the acrylic monomers remaining in said toner is 0.001 part by weight based on 100 parts by weight or less of the binder resin component in the toner (10 ppm). At least one component of the mixture of acrylic monomers has a Q-value of 0.5 to less than 1.0 and the other has a Q-value of 0.3 to less than 0.5.This toner is excellent in the anti-off-set property to a fixing roller surface, good in fixability, giving high image density and little odor.

C. of 2.times.10.sup.3 or higher to below 5.times.10.sup.5 [dyne/cm.sup.2 ] as measured in the frequency range of 1.times.10.sup.-2 -1 (Hz); a loss modulus G".sub.120-200 at 120.degree.-200.degree. C. of 2.times.10.sup.3 or higher to below 5.times.10.sup.5 [dyne/cm.sup.2 ] as measured in the frequency range of 1.times.10.sup.-2 -1 (Hz); a dynamic modulus G'.sub.200 at 200.degree. C. and a frequency f satisfying an approximated linear relationship according to the least squares method of: logG'.sub.200 =a.multidot.log.multidot.f+log b, wherein a denotes a positive number of 0.25 or smaller and b denotes a constant; and a ratio (G'.sub.200)/(G'.sub.120) of below 0.25 wherein (G'.sub.200) denotes a dynamic modulus at 200.degree. C. and (G'.sub.120) denotes a dynamic modulus at 120.degree. C. respectively at a frequency of 1 (Hz).

    摘要： A developer for developing electrostatic latent images is constituted by a toner, and negatively chargeable spherical resin particles having an average particle size of 0.03-1.0 micron and a volume resistivity of 10.sup.6 -10.sup.12 ohm.cm. The toner may comprise toner particles and hydrophobic inorganic fine powder, which is generally used in a larger amount than the negatively chargeable spherical resin particles. The negatively chargeable spherical resin particles function to provide a toner image which is faithful to an electrostatic latent image formed on a photosensitive member while preventing toner-sticking onto the photosensitive member preferably in combination with a contact-charging means for charging the photosensitive member.
