摘要： A toner and a carrier are so combined together as to substantially satisfy the following formula (1), ##EQU1## wherein Qmax is a maximum amount of electric charge (.mu.C/g) of the toner, V.sub.T/C is a contact potential difference (V) of the toner to the carrier, .tau.r is a relaxation time constant (sec) of the toner, .tau.g is a charging time constant (sec) of the toner, and k is a coefficient (F) determined depending upon the kinds of the toner and the carrier. This method makes it possible to so combine the toner and the carrier together that the amount of electric charge of the two-component developing agent becomes a maximum based on the contact potential difference (V.sub.T/C) of the toner to the carrier.
