Title:
IMAGE FORMING DEVICE
Document Type and Number:
Japanese Patent JP2023004696
Kind Code:
A
Abstract:
To acquire sufficient bond strength even without setting a heating temperature at the bonding time to an extremely high temperature.SOLUTION: An image forming device includes: image forming means for forming a toner image on a sheet by using printing toner, and for coating a powder adhesive agent to a sheet; fixing means having a first rotary body pair for forming a first nip part, and for fixing the toner image to the sheet by heating and pressurizing the sheet conveyed from the image forming means while holding and conveying it by the first nip part; folding means for folding the sheet conveyed from the fixing means with the surface where the powder adhesive agent is coated being inside; and bonding means having a second rotary body pair for forming a second nip part, and for bonding the sheet by the powder adhesive agent by heating and pressurizing the sheet folded by the folding means while holding and conveying it by the second nip part. A peak value of the pressure which the second rotary body pair applies to the sheet at the second nip part is larger than a peak value of the pressure which the first rotary body pair applies to the sheet at the first nip part.SELECTED DRAWING: Figure 11
