Recent observations of blazars by X- and gamma-rays show that blazars exhibit rapid time variations. We use the synchrotron-self-Compton (SSC) model to simulate the time variations of the energy spectra of radiation and electrons; we solve the kinetic equations of electrons and photons simultaneously, including a simple model of electron acceleration which mimics the shock acceleration. Electrons escaping from the acceleration region are injected into a cooling region where electrons emit radio through very high energy gamma-rays via SSC. The time evolution of the energy spectra of electrons and photons are shown, when low energy electrons (γ~2) are supplied in the acceleration region and accelerated up to γ~107. Then TeV gamma-rays are emitted as observed from Mrk 421 and Mrk 501. .
