Archive post format page

Is there a conditional tag for archive post format ? For example, If i have a permalink from get_post_format_link('aside') function and i click on it, i go to post archive only with aside format. Question is, how can i recognize this page in archive.php file ? I find is_post_type_archive(), but it doesn´t work.
Here is example of archive pageb: http://www.exampledomain.en/?post_format=image
