    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： An image forming apparatus uses an electrode member with apertures therein through which toner is passed according to an image to a support medium. A toner carrier member has a low friction layer contacting the surface of an electrode member. The low friction layer is made of molybdenum disulfide or a similar solid lubricant. Friction between the surface of the low friction layer directly contacting the electrode member and toner particles is so small that the attachment force of the toner particles is small. Therefore, by using a small potential the electrode can be controlled for selectively passing toner particles through the apertures. As a result, a low cost driving element can be used for the image forming apparatus.
