Toner for electrostatic charge image developing, developer for electrostatic charge image developing, and image forming apparatus

An image forming apparatus, comprising an image carrying body, an charging means for charging a surface of the image carrying body, an exposing means for forming an electrostatic latent image on a surface of the charged image carrying body based on image information, a developing means for developing the electrostatic latent image with a developer containing a toner to form a toner image on a surface of the image carrying body, a transferring means for transferring the toner image onto a surface of a recording medium from the surface of the image carrying body, and a fixing means for fixing the toner image transferred onto the surface of the recording medium by heating and pressing, to form an image, wherein the toner is a toner for electrostatic charge image developing having a core layer which contains a first binder resin and a coloring agent, and a shell layer which contains a second binder resin and covers the core layer, and satisfies the following equation (1) and the following equation (2),

• 2.0×105≦G′(60)≦4.0×106 Equation (1)
• 10≦G′(60)/G′(80)≦40 Equation (2)
• and wherein, in the equation (1) and the equation (2), G′(60) represents a storage elastic modulus (Pa) of the toner for electrostatic charge image developing measured under the conditions of a temperature of 60° C., a vibration frequency of 6.28 rad/sec, and a strain amount of 0.01 to 0.5%, and G′(80) represents a storage elastic modulus (Pa) of the toner for electrostatic charge image developing measured under the conditions of a temperature of 80° C., a vibration frequency of 6.28 rad/sec, and a strain amount of 0.01 to 0.5%.
