PROBLEM TO BE SOLVED: To provide a solid lubricant-coating device and an image forming apparatus in which, even when an image is formed at a high speed, the occurrence of image noises such as an image blur and image flowing is sufficiently prevented. SOLUTION: The solid-lubricant coating device 7 is provided with a solid lubricant 71 to be applied to the surface of a latent image-supporting member 1; a supply roller 72 for scraping and supplying the solid lubricant onto the surface of the latent image-supporting member by self rotation; a pressing unit 73 for pressing the solid lubricant onto the supply roller; a flattening unit 74 for forming a thin film of the supplied solid lubricant on the surface of the latent image-supporting member; and a cleaning unit 75 for removing the residual toner on the surface of the latent image-supporting member and recovering the solid lubricant thin film on the surface of the latent image-supporting member, wherein, when a thickness of the solid lubricant thin film formed on the latent image-supporting member, immediately before the supply roller in the rotation direction of the latent image-supporting member is designated as thickness A(nm) and a thickness immediately after the flattening unit is designated as thickness B(nm), the thicknesses A and B satisfy following relational formulas: B-A≥8 and A≥4. The image forming apparatus 10 is provided with the solid lubricant coating device. COPYRIGHT: (C)2011,JPO&INPIT
