Abstract
It is to provide a toner for developing static charge and a process for producing the same that is excellent in peelability of the fixing sheet, adhesion of the fixed image, bending resistance of the fixed image, Dispersibility of the releasing agent in the toner and transparency on an OHP sheet, and can provide a high quality fixed image, as well as a developer and a process for forming an image. It relates to a toner for developing electrostatic charge of the invention including a coloring agent and a binder resin and a process for producing the same, wherein the relaxation modulus of elasticity G(t) at a relaxation time t=10.times.Dt (wherein Dt represents a heating time on fixing) obtained from measurement of dynamic viscoelasticity is adjusted to a range of from 2.0.times.10.sup.2 to 3.0.times.10.sup.3 Pa, or the relaxation modulus of elasticity G(t=0.01) at a relaxation time of 0.01 sec obtained from measurement of dynamic viscoelasticity is adjusted to a range of from 2.0.times.10.sup.2 to 3.0.times.10.sup.4 Pa, and the ratio G(r) (G(t=0.01)/G(t=0.1)) of the relaxation modulus of elasticity G(t=0.01) to a relaxation modulus of elasticity G(t=0.1) at a relaxation time of 0.1 sec is adjusted to a range of from 1.0 to 18.0, as well as a developer and a process for forming an image using the developer.
