摘要:
Toner is supplied from a toner container to a developing part that causes the toner to adhere to a latent image formed on a latent image carrying member and develops the latent image, a pre-toner-supply operation of supplying a predetermined amount of toner to the developing part is carried out, a fog detecting image is formed and fog is detected in the fog detecting image, a toner supply amount to be supplied to the developing part is determined based on the fog detected in the detecting and an operational status of the developing part since the toner was supplied to the developing part the last time, and the toner supply amount of the toner determined in the determining is supplied to the developing part.
摘要:
A toner supplying method for supplying toner from a toner container to a developing part that causes toner to adhere to a latent image formed on a latent image carrying member and develops the latent image, includes detecting a toner amount in the developing part as being equal to or less than a predetermined toner amount value; forming a fog detecting image in a case where the toner amount in the developing part is equal to or less than the predetermined toner amount value, and detecting fog; and determining based on the detected fog whether to execute a toner ejecting process of ejecting the toner remaining in the developing part toward the latent image carrying member before supplying the toner to the developing part from the toner container.

An image forming apparatus includes an image carrier on which a latent image is formed, a charging device that charges the image carrier, an exposing device that irradiates the image carrier, thereby forming a latent image on the image carrier, a developing device that develops the latent image into a visible image by using a monocomponent developer that is carried and transferred by a developer carrier and that is charged to a predetermined polarity, and a toner supply container that is installed in the developing device for toner supply. Used old toner is conveyed from the developing device to the toner supply container and mixed with unused new toner within the toner supply container and thus a mixed toner is produced, and the mixed toner is supplied to the developing device.

摘要:
A toner supply method includes detecting whether a remaining toner amount in the development device is equal to or greater than a first remaining amount, supplying a first supply amount of toner to the development device in a first supply mode when the remaining toner amount is not greater than the first remaining amount, detecting whether the remaining toner amount in the development device is equal to or greater than a second remaining amount smaller than the first remaining amount, and supplying a second supply amount, smaller than the first supply amount, of toner to the development device in a second supply mode when the remaining toner amount is reduced to or below the second remaining amount.

摘要:
An image forming apparatus, including an image developer to develop an electrostatic latent image and a toner provider to provide a toner from a toner container to the image developer in a direction of gravitational force. The toner container is capable of taking a first position of directing a toner outlet in a horizontal direction; a second position of directing the toner outlet in a direction of gravitational force; and a position of being removed, directing the toner outlet upward relative to the horizontal direction when further rotating from the first position. The toner container includes a main cap member to close the toner outlet when taking the first position and the position of being removed; and a sub-cap member to cover the main cap member while the toner container is displaced from the first position to the position of being removed.
