A controller which causes a light emitting element to continuously perform minute emission for a plurality of dots in a level in which toner is not attached to a non-image section on an image bearing member is provided. The controller controls a first driving current for an image section and controls a second driving current used to perform the minute emission by the light emitting element in the non-image section several times in one job. In the image section, a driving current obtained by adding the first driving current to the second driving current is supplied so that the light emitting element emits light.

Color image forming apparatus

An image forming apparatus includes a photosensitive member, a charging unit, an image exposure unit configured to form image portion potential by exposing the photosensitive member to light, a weak exposure unit configured to form non-image portion potential by exposing the photosensitive member to weak light having a lower exposure amount than the light for forming the image portion potential, and a developer bearing member configured to carry developer, wherein a relationship of Ldev&#x3c;Lvd&#x3c;Lbg is satisfied, where the photosensitive member exposed to the weak light by the weak exposure unit has a weak exposure area having a length of Lbg in a photosensitive member longitudinal direction, a length of the developer carried by the developer bearing member in the photosensitive member longitudinal direction is Ldev, and the photosensitive member charged by the charging unit has a charging area having a length of Lvd.

Image forming apparatus

The present invention relates to a developing unit including a developer container accommodating a developer; a developer bearing member bearing the developer supplied from the developer container; a magnetic-field generation member disposed in the developer bearing member, the magnetic-field generation member having a magnetic-field generation area generating a magnetic field for attracting the developer to the developer bearing member; and a sealing member disposed at the developer container, the sealing member preventing the developer from leaking from a gap between a longitudinal end of the developer bearing member and the developer container. An end of the magnetic-field generation area of the magnetic-field generation member is disposed inside an inner end of the sealing member in the longitudinal direction of the developer bearing member. The developer bearing member develops a latent image formed on the image bearing member with the developer while keeping in contact with the image bearing member.

Developing unit and process cartridge

An image forming apparatus includes an image bearing member that bears a developer image, a transfer apparatus that transfers the developer image, a charge apparatus, an exposure apparatus that exposes the surface of the image bearing member with light to form a latent image, and a developing apparatus that collects and supplies the developer to the latent image to form the developer image, in which an image formation area is divided into an image part and a non-image part where the developer image is not formed, the exposure apparatus exposes the non-image part with light at an exposure amount lower than an exposure amount with respect to the image part, and the charging apparatus charges the image bearing member and the exposure apparatus exposes the image part and the non-image part with light in a state in which the developer remains on the image bearing member.

An image forming apparatus includes a first toner image bearing member, a second drum, an intermediary transfer member, or belt, a secondary transfer member, a toner charging member, and a controller for controlling an operation in a single-color image forming mode and an operation in a multi-color image forming mode. The controller effects, in a post-processing operation after the operation in the single-color image forming mode in which the toner image is formed on the first drum is ended, control such that a separation state between the drum and belt is switched to a contact state between the image bearing member and belt and then the toner deposited on the toner charging member is collected onto the second drum via the belt and then is collected by a cleaning device provided for the second drum.

Image forming apparatus having duel color image forming control modes

In a color image forming apparatus, the amount of light of an exposure unit for a weak exposure is changed according to a remaining service life of a photosensitive drum when the weak exposure is performed for the background area of a corresponding photosensitive drum by using the exposure unit.

The image forming apparatus includes a photosensitive drum and a light emitting device. In the rotational axis direction of the photosensitive drum, the width of the weak light exposure region on the photosensitive drum in which an exposing device emits weak light is larger than the width of a region corresponding to the width of a recording medium on which an image is formed, but smaller than the width of a region on the photosensitive drum charged by a charging roller.

An image forming apparatus includes a control device configured to control an information signal that notifies a user of a coming shortage of the developer in a developer storage portion or a usage limit of the developing device. The control device can transmit the information signal in such a way that the amount of the developer remaining in the developer storage portion at the transmission timing of the information signal is variable according to a developer consumption amount per unit number of recording material sheets.

A game apparatus includes a first LCD and a second LCD, and on the first LCD, a two-dimensional game screen including objects positioned in a two-dimensional coordinate is displayed. When a two-dimensional coordinate of a specific object out of the objects positioned in the two-dimensional coordinate satisfies a predetermined condition, a three-dimensional coordinate of each of the objects is calculated on the basis of the two-dimensional coordinate of each of the objects. The object is modeled in the calculated three-dimensional coordinate, moved by a predetermined animation, and then shot by a virtual camera. Accordingly, a game screen of an image (animation) of the three-dimensional virtual space shot by the virtual camera is displayed on the second LCD.

Game apparatus, storage medium storing a game program, and game controlling method

An image forming apparatus includes a developing device for developing a latent image formed on an image bearing member on the basis of image information, into a developed image with a developer, the developing device including a developer accommodating portion for accommodating the developer and a stirring member for stirring the developer in the developer accommodating portion; an optical remaining amount detecting device for detecting a remaining amount of the developer in the developer accommodating portion, by passing light through an inside of the developer accommodating portion; a consumption amount calculation device for calculating information relating to a consumption amount of the developer on the basis of the image information; and an outputting device for outputting an information signal indicative of a developer remainder which is either one of a developer remainder based on a detection result of the optical remaining amount detecting device and a developer remainder based on the information relating to the consumption amount provided by the consumption amount calculation device, selected in accordance with information relating to continuous drive time of the stirring member after start of drive thereof during image forming operation.
