Recently, the numbers of discoveries of AGNs in GeV and sub-TeV energy bands have increased rapidly. Many simultaneous multiwavelength campaigns for AGN are performed and physical mechanisms are discussed aggressively. We select four Fermi AGNs from three sub-class of blazars, and discuss the quasi-simultaneous multiwavelength spectra using a simple leptonic jet model. For two HBLs (H 2356-309 and PKS 2155-304), the SEDs can be explained by a one-zone synchrotron self-Compton (SSC) scenario, and obtained parameters are almost in the range of typical HBL values. In the case of LBL (PKS 0537-441) and FSRQ (3C 279), our SSC model cannot explain the observed SEDs, and may require an introduction of another component, such as inverse Compton radiation with external photons.
