Do the angels forget the sins of the repentant?

If a servant repents sincerely, Allah forgives his sins and transforms his evil deeds into good ones, as mentioned in the verses: "Except for those who repent, believe and do righteous deeds. For them Allah will change their evil deeds into good ones" and "Indeed, good deeds do away with evil deeds." As for the angels forgetting sins, this is not a concern for the repentant one, and there is no text that confirms or denies it.
