PURPOSE:To collect scattered magnetic toner by providing in the main body of a copying machine a roller or a sheet having a uniform magnetic force on the whole surface. CONSTITUTION:One or plural rollers or sheets having uniform magnetic force on the whole surface are installed in the main body of a copying machine, for example, on the inside part of lateral frames. This roller is obtained by forming a resinous material mixed with a hard magnetic powder into a cylinder and magnetizing this. Magnetic toner scattered during a copying process can be collected by utilizing the magnetic force of such a roller or sheet. |
