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.

An electronic device includes a housing that houses a movable member inside the housing, and a shock absorbing member that reduces a shock to the movable member. The shock absorbing member holds the housing on an inner side of the shock absorbing member and includes at least one of a protrusion protruding in a direction along a movable direction of the movable member or a depression depressed in a direction along the movable direction on an outer side of the shock absorbing member.

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.

An image forming apparatus and process cartridge employed in same which, when contact charging processing is implemented employing a brush roller, suppresses the generation of localized excessive discharge and suppresses a state of localized excessive discharge on a photosensitive drum surface. Charging means is configured from a brush roller in the surface of which a brush is formed, drive means for rotationally driving the brush roller, and a power source for applying a prescribed charging voltage to the brush roller, and uniformly charges the surface of the latent image carrier by bringing the brush roller into contact with the surface of the latent image carrier. The outer diameter of the latent image carrier is in the range 16 [mm] or more and 34 [mm] or less, the outer diameter of the brush roller is in the range 6 [mm] or more and 24 [mm] or less, and the outer diameter of the latent image carrier and the outer diameter of the brush roller are set so that the sum of the outer diameters thereof is 40 [mm] or less.

A developing apparatus with a developing roller for conveying toners held on its surface to a developing area opposite to an image carrying member, the surface of the developing roller being moved upward from below in the developing area; a regulating member for regulating an amount of the toners to be conveyed to the developing area by the developing roller; a plate-shaped charging member for charging the toners; and a voltage applying device for applying a voltage to the charging member.
摘要:
A developing apparatus according to the present invention for developing an electrostatic latent image formed on an image carrying member has a developer carrying member arranged opposite to an image carrying member and holding a developer, and a voltage applying device applying an AC voltage to the developer carrying member, wherein the AC voltage has a first peak potential and a second peak potential, the first peak potential being a peak potential on the side of development for supplying the developer to the image carrying member, the second peak potential being a peak potential on the side of recovery for returning the developer to the developer carrying member, and a voltage waveform of the AC voltage always has two straight line portions which differ in slopes while changing from the first peak potential to the second peak potential and/or from the second peak potential to the first peak potential.
