taxonomy.php

Great theme! I really like it. Thank you.
I want to make a taxonomy pages like the appearance of single.php(posts page). So I copy the content of single.php and past it in taxonomy.php.

taxonomy.php

<?php get_header(); ?>
<div id="primary" class="content-area col-lg-8 col-md-8 col-sm-12 col-xs-12">
  <main id="main" class="site-main" role="main">

  </main><!-- #main -->
</div><!-- #primary -->

<?php get_sidebar(); ?>
<?php get_footer(); ?>

However, a header image appears on a taxonomy page.
How can I make the appearance of taxonomy.php like a single.php(posts page)?
