I think getDeclaringType() should match your need. It's implemented on
IMember (IField super-interface).

Note that documentation of this method sounds really wrong and I've
opened a bug for this: https://bugs.eclipse.org/bugs/show_bug.cgi?id=169114

Ooops, forget my previous answer, I misunderstood getDeclaringType()
behavior. I've also invalidated the bug...
My mind seems not to work very well between Christmas and New year feast.

In fact, it seems you cannot directly get the IType for the field's
type, but only its signature using field.getTypeSignature().

Then for BinaryField, it's easy to get corresponding IType using
following code:
String typeSignature = field.getTypeSignature();
field.getJavaProject().findType(Signature.toString(typeSigna ture))

For SourceField, it's a little bit more tricky as the type signature is
not resolved...

IField field;

IType type = (IType) field.getParent()
