The darts legend's camp are said to have contacted lawyers over the poor edit of his behaviour in the jungle, according to The Sun.
"The edit's been so unfair," Bristow's son James said. "My dad's no bully, but they've painted him as a real nasty piece of work."
Bristow has been seen having a few confrontations in the jungle so far, including making Helen Flanagan cry over comments about her skin.
"I am really pissed off with the way dad's been made to look," James Bristow added. "The edit's been totally unfair and I know his manager is talking to lawyers about it.
"The feeling was that things can't get any worse - otherwise we will go for ITV and cause them huge problems.
"I understand this is a TV show on for entertainment purposes - and dad knew what he was getting himself into. But he's not a bully. He has a 21-year-old daughter himself, so would never be intentionally cruel to anyone else's.
"They've painted him as a real nasty piece of work at points, which is so unfair and frustrating to watch."
Eric Bristow's spokesman Steve Mottershead has said that the producers appear to have improved their portrayal in recent days.
He said: "They seem to have done a better job since people tweeted it wasn't fair. They saw it was strange what was happening in the way they were portraying Eric.
"It wasn't just coming from us as his representatives, it was coming from people on the street, and ITV took notice.
"It confused people that they were portraying him as this bad guy and then others were coming out of the jungle saying he was [a] lovely fella."
An ITV source said: "We haven't heard from Eric's lawyers. We always make a fair representation of what goes on in the camp. If something hasn't been said, we can't include it in the programme."
Eric Bristow has reached the final four of the ITV competition alongside Charlie Brooks, Ashley Roberts and David Haye.
