Recently, we have derived the leading and subleading isospin-breakingthree-nucleon forces using the method of unitary transformation. In the presentwork we extend this analysis and consider the corresponding two-nucleon forcesusing the same approach. Certain contributions to the isospin-violating one-and two-pion-exchange potential have already been discussed by various groupswithin the effective field theory framework. Our findings agree with thepreviously obtained results. In addition, we present the expressions for thesubleading charge-symmetry-breaking two-pion exchange potential which were notconsidered before. These corrections turn out to be numerically important.Together with the three-nucleon force results presented in our previous work,the results of the present study specify completely isospin-violating nuclearforces up to the order $q^5/\Lambda^5$, where $q$ ($\Lambda$) denotes the soft(hard) scale.Comment: 25 pages, 12 figure
