considering that espers has only one power

An esper can have only one esper ability, but IB and IT aren't esper abilities. I don't recall any limit about how many powers unrelated to both science and magic an esper can have.

the case of Touma is special, he may have the body changed, but there is some evidence in the series that says it has AIM field?

There are evidences that IB is not an esper ability (vol 6 epilogue). Touma is an esper, but havin a right hand that negates any supernatural power is absolutely normal that he doesn't emit any AIM field.
