Claim:
An image forming apparatus, comprising: an ink applicator unit to selectively apply ultraviolet (UV) curable ink on a media; a media support unit to support the media to receive the UV curable ink; and a UV radiation curing device to cure the UV curable ink on the media, including: a UV radiation source module to emit an electromagnetic spectrum; and a dispersion member to separate ultraviolet electromagnetic radiation subtype C (UVC radiation) from at least one of ultraviolet electromagnetic radiation subtype A (UVA radiation) in the electromagnetic spectrum and ultraviolet electromagnetic radiation subtype B (UVB radiation) in the electromagnetic spectrum, to apply the UVC radiation to the UV curable ink on the media, and to subsequently apply at least one of the UVA radiation and UVB radiation after the UVC radiation is applied to the UV curable ink on the media.
