PURPOSE: To provide a pressure-fixing microcapsule capable of being easily produced, sufficient in pressure fixability, without offsetting a roller and good in stability.

CONSTITUTION: A microcapsule 1 consists of a first capsule 5 and a second capsule 6 in the first capsule. The capsule 5 contains the first component of a two-pack mixed curing resin, and the capsule 6 contains the second component. The microcapsules 1 are accumulated on a substrate, then the first capsule 5 and second capsule 6 are broken when pressed by a fixing device, the resins flowing out respectively from the first and second capsules 5 and 6 are mixed and cured, hence the contents of the capsules are fixed with a sufficient power, and fixability is improved.
