This prompted him to find a solution and experiment with photoconductivity and electro-photography.
It took Carlson ten years to convince a company to accept his invention. He was rejected by companies like GE, IBM, Kodak and RCA.
In 1947 he finally sold the commercial rights to his invention to the now famous Xerox Corp. Eleven years later, Xerox introduced its first office copier.
