    摘要： A developer supply device is provided, which includes a transfer board including an activating section and an always-transferring section. The activating section is disposed in a position close to a developer holding member and lower than a position where development agent is transferred onto the developer holding member. The activating section is supplied with an activating voltage for making the development agent leave a developer transfer path and drop into the developer storage section during an activating process performed at an initial stage of a developer transferring operation while supplied with the transfer bias voltage after the activating process. The always-transferring section is disposed across a position facing the developer storage section to a position lower than and adjacent to the activating section, and always supplied with a transfer bias voltage during the developer transferring operation.

    摘要： A heating apparatus includes a heater, a current-feed switching circuit configured to switch turning-on/off of current-feeding from an AC power source to the heater, thereby feeding current from the AC power source to the heater at a predetermined current-feed ratio, a temperature detector configured to detect a heating temperature of the heater, anda current-feed controller configured to control the current-feed ratio of the current-feed switching circuit such that the detection temperature of the temperature detector falls within a target range. The current-feed controller performs at least one pair of ON lock current-feed control to fix the current-feed ratio to almost 100% in a first period and OFF lock current-feed control to fix the current-feed ratio to almost 0% in a second period every predetermined control period of the current-feed switching circuit.
