Nitrogen exhibits half filled(1s2 2s2 2p3) which gives more stability to the atom....so it becomes difficult to remove electrons from it and hence the IP required is more than that of oxygen's IP.....

Further, removal of one electron from Oxygen atom is relatively easy because it results in half filled stable p orbital configuration.
nitrogen has the half filled configuration..
and we know that half filled configuration is always stabler..
That's why ionisation energy of Nitrogen is more than Oxygen.
