We have investigated the influence of strong magnetic fields at the center of the quark stars which is an impact to shape of stars by using Einstein's theory of gravity, which uses the EoS CIDDM model. Our focus in this study is to compare the results of the deformation degree of quark stars from theory of gravity Einstein and Rastall, where on Rastall gravity introduced degree of freedom λ, where we use variations of λ = 1, 2, 3, 4 and 5, where Rastall gravity will reduced to Einstein theory of gravity at the value of λ = 1. We obtained for each EoS with different values of κ 1 indicate the degree of deformation tends toward prolate at the maximum mass of the same quark star for the both theories, the most significant difference on Rastall gravity is the maximum mass of quark stars increases with the high value of the λ we set.
