The charge and transition form factors of pions (F-pi, F-pi gamma, and F-pi
gamma*) are studied in the light-front quark model (LFQM). We find that ou
r results for F-pi and F-pi gamma agree well with experiment. Furthermore,
the mixing of eta and eta ' is considered. We also calculate F-eta gamma an
d F-eta ' gamma and compare them with the data.
