摘要： A hotmelt-adhesive fiber sheet having a high adhesion onto paper, clothes ,timbers, metals, etc. is obtained by subjecting (1) a termpolymer of ethylene-acrylic acid ester-maleic anhydride, from which microfine fibers have not so far been obtained due to inferior spinnability since the terpolymer has a high frictional force against metals and is liable to generate static electricity, and (2) a thermoplastic resin having a melting point higher by 30.degree. C. or more than the melting point of the terpolymer, to conjugate spinning according to a melt blown process, followed by making up the conjugate fibers into a web without using any spinning oiling agent and heat-treating the web.

摘要： When an input image is to be formed on a sheet conveyed to a transfer roller, the exposure section is controlled and deviation correction is performed to offset the image forming position across the width of the sheet in response to the result of detection by a deviation sensor. By contrast, when pattern images are to be formed on a sheet in response to the instruction of the main control section, the image forming control section does not perform deviation correction in the process of forming a pattern image.
