Arthur made the claims on camera and Maloney told Heat that he was surprised he felt that way.
"People are saying I'm two-faced," he said. "I didn't know he'd said that. I feel like I'm an easy target, to be honest.
"I mean, I'm going on tour with James and I didn't know anything about that. I don't know... That's totally shocked me, that."
Of claims that he has shouted at members of the production staff, Maloney added: "It's more like the other way round!
"You've got 12 people knocking on your door, all telling you you've got to be somewhere. I'm not in a position to speak to anyone in a derogatory manner. I'm grateful to be here."
The singer said: "I'm keeping my feet on the ground and not doing anything wrong. Because I'm not doing anything wrong, maybe that's why they're printing lies about me.
"I'm the same person off-camera as I am on... All the negativity and crap I've been getting - people trying to bring me down and maybe force me to quit - it's not going to happen.
"No way. I've worked too hard just for somebody to take it away from me."
Regarding claims that he has been late for rehearsals, Maloney countered: "I'm always at rehearsals and I'm always punctual.
"I worked in a call centre job for five years and I have never, ever been late, so why would I now in The X Factor? I just wouldn't do it."
"I've been getting demand letters for a loan that I took out and I'm like, 'How can I afford to vote for myself when I can't even afford to pay the bills?' I honestly haven't got the time. Or the credit."
