1. A resin particle having an exothermic peak observed, where differential scanning calorimetry is performed by heating the resin particle at a temperature rising rate of 5° C./min from 100° C. to 350° C. in an air atmosphere, wherein the resin particle satisfies at least one configuration selected from the group consisting of a Configuration (1) and a Configuration (2), as follows:
Configuration (1): among the exothermic peaks, an exothermic amount at the exothermic peak having the largest peak area is 2,000 mJ/mg or more and 25,000 mJ/mg or less;
Configuration (2): an absolute value of a difference between a compressive elasticity modulus where the resin particle is compressed by 10% and the compressive elasticity modulus where the resin particle heated at 200° C. for 10 minutes is compressed by 10% is 180 N/mm2 or more.
