Bothroyd arrived on a free transfer from Cardiff in the summer but has been in and out of an Rs side who have dropped into the relegation zone after a poor run of results.
With new arrivals expected, Bothroyd has been linked with a move away during the transfer window but he told London24.com: "It's all just been rumours. I don't want to go anywhere, I've got a lot of belief in myself and I want to be successful at QPR.
"New signings don't bother me, to be a successful team you have to have a big enough squad. You have to welcome it and raise your own game.
"It has been frustrating for me, I scored 20 goals last year but I haven't reached that form this season. There's always going to be criticism and I accept that, but I believe in myself. Some of the best strikers in the world go through bad patches - that's football.
"It can be difficult in your first season, I think a lot of strikers before me have discovered that. Look at Fernando Torres and Andy Carroll this season.
"I've worked with (new boss) Mark Hughes before and he's a terrific manager. The players know what he wants and they give it to him."
