On climb out around 3;000 feet with the Captain (CA) flying; the CA stated the ailerons were strange. He asked me to confirm so I took the flight controls and felt at least double the normal aileron force required. CA remained Pilot Flying (PF) for the remainder of the flight. He took a few more turns to assess the feeling; monitored hydraulics and flight controls pages for problems and none were noted. Due to our proximity to [our] destination requiring the visual the CA suggested and I concurred on a diversion. Before proceeding with that; I called up the Flight Attendant (FA) and used the lavatory. Upon return to the cockpit I acquired ATIS; loaded and built the ILS 18L; FA's were advised as I went to the lavatory; I saw an ACARS free text from our dispatcher asking about [our situation]; so I considered the company notified; the Captain briefed a visual and we accomplished the descent check. At some point approach [was notified of our situation.] We were cleared for the visual; the before landing checklist was completed and we landed uneventfully. The CA took the radios for coordination; advised fire/rescue we didn't need assistance or brake check; I accomplished the after landing flow; called ops; acquired [a] gate and proceeded to coordinate with ground for taxi to the gate. Upon arrival at the gate all ops were normal.
Reporter stated cause was unknown; and the aileron force seemed normal on taxi in.
A CRJ-700 First Officer reported a flight control malfunction with the ailerons.
