Importers are a PEP 302 API. In the context of pkgutil, they are path hooks (see http://www.python.org/dev/peps/pep-0302/#id24), aka path importers. A path hook is a callable that takes a path and returns a finder. Path hooks are stored in sys.path_hooks and the finder resulting from a matching path importer is stored in sys.path_importer_cache.
pkgutil also refers to PEP 302 finders as "importers". To be honest, the import-related nomenclature is a mess.
While you can use pkgutil.ImpImporter as a path hook, instances can also be used as metapath hooks; if you don't pass anything to ImpImporter, the resulting object acts more like a PEP 302 metapath hook that wraps the "default" import process.
