@chaot,
The existence of page_styles.css suggests you have an epub created by a calibre conversion. If you don't want it created you should review your calibre conversion settings - specifically the 4 x Margin settings on the Page Setup page. I have all mine set to 'Unchanged' and the extra page_styles.css is not created during conversion.
Caveat: If your epub contains embedded fonts then converting it will still create page_styles.css file and all the @font-face css statements will have been moved into it.
