We investigate the tensor form factors of the baryon octet within the framework of the chiral quark-soliton model, emphasizing those of the nucleon, taking linear 1/N{sub c} rotational as well as linear m{sub s} corrections into account, and applying the symmetry-conserving quantization. We explicitly calculate the tensor form factors H{sub T}{sup q}(Q{sup 2}) corresponding to the generalized parton distributions H{sub T}(x,{xi},t). The tensor form factors are obtained for the momentum transfer up to Q{sup 2{<=}}1 GeV{sup 2} and at a renormalization scale of 0.36 GeV{sup 2}. We find for the tensor charges {delta}u=1.08, {delta}d=-0.32, and {delta}s=-0.01 and discuss their physical consequences, comparing them with those from other models. Results for tensor charges for the baryon octet are also given.
