摘要:
An image forming apparatus has a movable image bearing member on which an unfixed image is formed, transfer device for transferring the unfixed image on the image bearing member onto a recording medium, fixing device for heating and fixing the unfixed image transferred by the transfer means on the recording medium. The fixing device has a driving rotatable member for conveying the recording medium. The recording medium during the transfer by the transfer device is conveyed by the driving rotatable member. The apparatus is provided with detecting device for detecting information regarding the peripheral velocity of the driving rotatable member, and control device for controlling the movement speed of the image bearing member on the basis of the result of the detection by the detecting device.

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.

In an image forming apparatus adapted to form images by employing a plurality of image bearing members, when a monocolor mode is selected, no toner image is formed on photosensitive drums of the colors other than the photosensitive drum on which a black toner image is formed. However, the photosensitive drums of the remaining colors continue to run while maintaining a speed difference in a four-full-color mode in relation to an intermediary transfer belt. As a result, some photosensitive drums reach their service life even if the toners contained in developing devices have not yet run out or even if images have not yet been formed on a predetermined number of transfer materials. To solve the problem, the peripheral speed of each of the photosensitive drums in the black monocolor mode for producing monochrome images is set to be faster than that in the full-color mode so as to make the peripheral speed virtually equal to the moving speed of the intermediary transfer belt.

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.

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.
