Patent ID: 7715775

Claim:
An image glossing apparatus comprising: first and second heating rotating members which contact each other to form a nip portion, a toner image on a recording material being heated in the nip portion, a surface of the second heating rotating member being rougher than a surface of the first heating rotating member; a cooling unit which cools the recording material, moved while contacting the first heating rotating member, before the recording material is separated from the first heating rotating member; and a mode performing unit which performs a high-gloss mode and a low-gloss mode, the recording material is conveyed to and heated by the nip portion such that the toner image contacts the first heating rotating member in the high-gloss mode, and the recording material is conveyed to and heated by the nip portion such that the toner image contacts the second heating rotating member in the low-gloss mode, wherein both a surface roughness Rz 1 of the first heating rotating member and a surface roughness Rz 2 of the second heating rotating member range from 0.5 μm to 20 μm, an irregularity mean spacing Sm 1 of the first heating rotating member ranges from 1 mm to 3 mm, an irregularity mean spacing Sm 2 of the second heating rotating member ranges from 50 μm to 500 μm, a surface roughness Ra 1 of the first heating rotating member ranges from 0.1 μm to 0.9 μm, and a surface roughness Ra 2 of the second heating rotating member ranges from 1 μm to 3 μm.
