A label sticking apparatus comprises, for example, three pushing devices. The pushing devices serve to press the label held by the sucking plate against an object to be labeled. The pressing device includes pressing rods. The pressing rods are held by a holding member with each one coil spring. A label pressing member is attached to the lower end of the pressing rod. The label pressing member has a hollow and tubular body made of a soft material. The holding member is attached to the forward end of a rod of an actuator comprising a cylinder etc. Under the holding member, a stopper for suddenly stopping the holding member is disposed.

Disclosed is a photosensitive material for the electrophotography, comprising as the charge-transporting substance a composition comprising an organic polysilane and a member selected from the group consisting of an electron-accepting substance, a diphenoquinone derivative, a low-molecular-weight hole-transporting substance, a high-molecular-weight polycyclic hindered phenol and an n-type charge-generating substance. Even if this photosensitive material is subjected to charging and light exposure repeatedly or irradiated with ultraviolet rays, quantities of charges of the surface voltage and residual voltage are very small, and the photosensitive material has an excellent resistance to the repetition of charging and light exposure operations and an excellent light resistance.

An apparatus for plating a metal strip in an electrolytic cell is provided with a supporting roll. The support roll is disposed apart from the deflector rolls by a predetermined distance and supports the metal strip in such a way that the catenary of the metal strip can be reduced. The distance is determined so that the catenary is 0.04 or less times of the distance between upper and lower electrodes in the electrolytic cell. When the metal strip is a steel plate having a density of 7.85.times.10.sup.-6 (kg/mm.sup.3), the predetermined distance l (mm) between the axis of the deflector roll and that of the supporting roll is subject to the following formula: ##EQU1## in which the distance between the upper and lower electrodes is .DELTA.D (mm), the thickness of the metal strip being t (mm), the width thereof being W (mm) and the tension applied to the metal strip being T (kg).
