PROBLEM TO BE SOLVED: To obtain a toner container or a developer container provided with a label which is not torn or which does not wrinkle by absorbing moisture by providing the toner container with an aperiodic part at one part of a spiral groove and the heat shrinkable film label covering the aperiodic part and heat- shrinking in follow up to the aperiodic part. SOLUTION: The spiral grooves is aperiodically formed at the outside circumference of the toner container. Specially, the aperiodic part 1a obtained by making a pitch between the grooves partially large (swollen) or small (recessed) in comparison with the uniform pitch is formed. Then, the aperiodic part 1a is covered with the shrinkable film. By making the shrinkable film shrink in follow up the recessed and swollen parts, the shrinkable film is fixed so that it is not moved left and right with respect to the spiral groove. That means, the part where the width of the gap between the grooves is swollen is formed and defined as the aperiodic part 1a. Then, the shrinkable label is fixed to the cylindrical toner container having the spiral groove at the outside circumference by being made to heat-shrink along the outside circumference including the aperiodic part 1a. |
