We compute electroweak form factors of the nucleon and photon transition form factors of non-strange baryon resonances up to the third resonance region in a model with instanton-induced interaction. The calculation is based on the Bethe-Salpeter equation for three light constituent quarks and is fully relativistic (U. Löring \it et al., Eur. Phys. J. \bf A10, 309 (2001)). Static nucleon properties and photon resonance couplings are in good agreement with experiment and the Q2-behaviour of the experimentally known form factors up to large momentum transfer is accounted for.
