摘要： In a charging device having saw-tooth electrodes for generating corona discharges, an amount of dust, toner, or paper dust attached to the tip end portions of saw-tooth electrodes is reduced. First to third pairs of saw-tooth electrode plates are disposed in a side-by-side fashion along the periphery of a photosensitive drum in which the first pair is disposed at an upstream side with respect to a direction in which the photosensitive drum rotates, the third pair at a downstream side, and the second pair at a central portion between the remaining two. A current flowing per a unit length of the second pair is set to 1.3 to 3 times as much as a current flowing per a unit length of each of the first and third pairs. The currents flowing per a unit length of the first and third pairs are set to be equal to each other.

摘要： The present invention provides a process and apparatus for readily and continuously producing foamed resin containers with labels by following a process sequence including the steps of supplying a sheet which bears label bodies printed in predetermined positions thereon, positioning a label body, punching the label body, and molding a foamed resin container with the label properly positioned. The invention further provides a process which allows for precise positioning of a label. Therefore, a thin and less stiff synthetic resin sheet can be employed for the label instead of a paper base. In addition, the label can be applied in a predetermined position on the foamed resin container without preliminarily rolling the label into a predetermined tubular shape.
