Abstract
A lenticular lens sheet manufacturing apparatus includes a transparent toner layer forming section and a lens forming section. The transparent toner layer forming section includes a photoreceptor drum, a charging section and a exposure section that form an electrostatic latent image on the photoreceptor drum, a developing section that forms a transparent toner image, a transfer section that transfers the transparent toner image to one side of a transparent substrate, and a fixing section that heats the transparent toner image transferred to one side of the transparent substrate to fix the transparent toner image, thereby forming a transparent toner layer on one side of the transparent substrate. The lens forming section pressurizes under heating the transparent toner layer formed on one side of the transparent substrate to shape the layer into a concavo-convex shape, thereby forming a lens layer having a concavo-convex shape on one side of the transparent substrate.
