A noncontacting power transfer apparatus, a noncontacting signal transfer apparatus(to be referred to below as a power coupler and a signal coupler, respectively), and a separate machine apparatus that uses these couplers are disclosed. The power coupler is composed of a primary side and a secondary side that are fixed to a static unit and rotatable unit of the machine apparatus, respectively, such that its output does not vary with arbitrary rotation by the rotatable unit. The signal coupler is composed of receiving side portion having a electric-to-light conversion device that converts an electric signal to an optical signal of rotational symmetry relative to the axis of rotation of the rotatable unit and a photoelectric conversion device that converts an optical signal to an electric signal. Accordingly, the rotatable unit can be supplied with power from the static unit even while rotating, and moreover, can communicate with the static unit. Further, the rotatable unit can be easily attached to the static unit and can remove from the static unit.

A method for making a photoconductive powder which comprises the steps of preparing fine particles of metal oxide or metal hydroxide by hydrolyzing a metal alkoxide or metal acetylacetonate; and immersing the fine particles into pigment containing suspensions to provide three types of composite particles. Each of the suspensions contains a respective pigment having a spectral absorption band within the wavelength region of a one of the primary colors of the additive principle. Each type of the resultant composite particles is composed of the fine particles of the metal oxide or metal hydroxide and the associated pigment as a principal component.
