Embossed multi-ply fibrous structures that exhibit a Geometric Mean Elongation of greater than 15.8% as measured according to the Elongation Test Method are provided.

An image forming apparatus includes: a needleless binding device configured to form a recessed or raised impression as a needleless binding part by performing needleless binding on a bundle of sheets; an environment sensor; and a controller configured to perform, based on a value detected by the environment sensor, control to display a confirmation image requesting a user to make confirmation on the needleless binding prior to execution of the needleless binding.

A hygienic thin-leaf paper includes a first sheet (10) including first embossed regions (30) in each of which first embossed protrusions (31) and first non-embossed protrusions (32) are included, the first sheet including first non-embossed regions (50) in each of which a first embossed protrusion (31) and a first non-embossed protrusion (32) are not included; and a second sheet (20) including second embossed regions (40) in each of which second embossed protrusions (41) and second non-embossed protrusions (42) are included, the second sheet including second non-embossed regions (60) in each of which a second embossed protrusion (41) and a second non-embossed protrusion (42) are not included. The first sheet (10) and the second sheet (20) are integrally laminated, the first embossed protrusions (31) include multiple first dotted embossed protrusions (31A) and multiple first linear embossed protrusions (31B), and the second embossed protrusions (41) include multiple second dotted embossed protrusions (41A) and multiple second linear embossed protrusions (41B). Each first non-embossed region (50) faces a given second linear embossed protrusion (41B), and each second non-embossed region (60) faces a given first linear embossed protrusion (31B).

A multi-ply tissue paper product includes at least four plies made of tissue paper base-sheet or non-woven. Two inner plies are positioned between a first outer ply on one side and a second outer ply on another side. The two inner plies are flat plies. The first and second outer plies include a micro-embossing pattern. Only one of the outer plies further includes a dcor embossing pattern. The multi-ply tissue paper product is configured to provide improved thickness and strength parameters with less use of paper fiber material.
