An image-forming toner and an image-forming method capable of forming a high-quality image over a long period of time, having both excellent excellent low-temperature fixability, high hot offset resistance, and good storage stability. And providing a process cartridge. A crystalline polyester resin (A), an amorphous resin (B), and a composite resin (C) including a condensation polymerization resin unit and an addition polymerization resin unit, and having a molecular weight distribution of 1000 to 10,000. The main peak has a half-width of 15000 or less, contains a chloroform-insoluble component, and the electrophotographic image-forming toner is stored in a thermostat at 45 ° C. for 12 hours and then subjected to Fourier transform. When measured by a total reflection method using an infrared spectroscopic analyzer, the peak height of the characteristic spectrum derived from (A) is defined as C, and the peak height of the characteristic spectrum derived from (B) Where R is R and C / R is 0.03 to 0.55.
