A charging roller is provided which has a simple construction without provision of a coating film and yet is capable of uniformly electrically charging the surface of a photoreceptor body and more advantageously suppressing adhesion and accumulation of fine particles. A charging roller production method is also provided. The charging roller (1) includes a roller body (2) having an outer peripheral surface (5) which includes a surface roughness component including a multiplicity of asperities and having a void volume Vv of less than 0.3 ml/m2, and a surface waviness component including a multiplicity of asperities having a lower frequency than the surface roughness component and having a void volume Vv of not less than 0.05 ml/m2 and not greater than 6 ml/m2, the void volumes Vv being each defined as the sum Vvc+Vvv of a core void volume Vvc and a dale void volume Vvv. The production method includes the step of finishing the outer peripheral surface (5) into a surface geometry satisfying the aforementioned requirements for the void volumes Vv by at least one of laser processing, wet blasting and dry blasting after polishing the outer peripheral surface (5).
