Electrostatic charge image developer, developer cartridge, process cartridge, image forming apparatus, and image forming method

An electrostatic charge image developer comprising:

• a toner including toner particles that contain a binder resin;
• and
• a carrier including magnetic particles and a resin layer that adheres to a surface of the magnetic particles,
• wherein, the binder resin contains a crystalline resin and an amorphous resin, the toner particles have a storage elastic modulus G′ of 1×108 Pa or greater in the temperature range of 30 to 50° C., and
• in a dynamic viscoelasticity measurement of the toner, in a case where a loss tangent tanδ at a temperature of 90° C. and a strain of 1% is represented by D1 (90), a loss tangent tanδ at a temperature of 90° C. and a strain of 50% is represented by D50 (90), a loss tangent tanδ at a temperature of 150° C. and a strain of 1% is represented by D1 (150), and a loss tangent tanδ at a temperature of 150° C. and a strain of 50% is represented by D50 (150),
• each of D1 (90), D50 (90), D1 (150), and D50 (150) is 0.5 or more and 2.5 or less,
• a value of D50 (150)−D1 (150) is less than 1.5, and
• a value of D50 (90)−D1 (90) is less than 1.0, and
• in the surface of the magnetic particles, an average unevenness interval Sm and an arithmetic mean roughness Ra satisfy 0.5 μm≤Sm≤2.5 μm and 0.3 μm≤Ra≤1.2 μm.
