The correct term is logogram or logograph. Hieroglyphs more commonly refer to the Ancient Egyptian writing system, whereas logogram and logograph are more general terms. Ideogram/graph refer to a specific type of logogram in which the character represents a specific idea or concept, but only a small minority of Chinese characters are ideograms.
