How to compare instances of Type for equality

Given two instances of Type:

Type type1;
Type type2;

How to can I check if they are equal?

I'm calling toString and comparing their values, as such:

if (type1.toString().equals(type2.toString())) {
    ....
}

I tested it with multiple and nested parameterized types and so far it seems to be consistent. But I would like to know if there is a formal way to do it.
