The nucleon`s strange form factors {ital G}{sup {ital S}}{sub {ital E}}({ital Q}{sup 2}) and {ital G}{sup {ital S}}{sub {ital M}}({ital Q}{sup 2}), and the neutron`s electromagnetic form factors {ital G}{sup {ital n}}{sub {ital E}}({ital Q}{sup 2}) and {ital G}{sup {ital n}}{sub {ital M}}({ital Q}{sup 2}), are obtained from the light-cone quark model including the quark anomalous moments due to the meson-loop corrections. The anomalous magnetic and strange moments of the constituent quark make significant contributions: Without them, {ital G}{sup {ital S}}{sub {ital M}}(0) vanishes, {ital r}{sup 2}{sub {ital S}} becomes positive, and the neutron charge radius is too small.
