ABSTRACT:
An electrophotographic apparatus utilizes solid developers of a plurality of colors for developing an electrostatic latent image. The solid developers are solid at normal temperature and are changed into liquid by heating. The liquid developers are supplied to the static latent image and develop it. The solid developers of a plurality of colors are accommodated within a single container in a predetermined order so that the electrophotographic apparatus can be simplified and made inexpensive.
