There is provided an apparatus having an exposure head including K light-emitting chips arranged along a rotation axis of a photosensitive body. Light-emitting elements to form a latent image are arranged in each light-emitting chip. The apparatus includes: a dividing unit that divides image data into K pieces of partial image data for the K light-emitting chips that are temporarily stored in memory resources; and a control unit that controls output of the K pieces of partial image data from the memory resources to the K light-emitting chips. The control unit controls allocation of the memory resources to the K light-emitting chips based on information indicating which ones of odd-numbered and even-numbered light-emitting chips of the K light-emitting chips are arranged on downstream side with respect to the photosensitive body which rotates.

Exposure-controlling apparatus and image-forming apparatus

An image forming apparatus that includes an image capturing unit capturing an image in front of the apparatus; a display displaying a screen; and a controller including one or more processors, the controller configured to function as: an acquisition unit acquiring a face image of a user from the image captured by the image capturing unit; an authentication unit authenticating, using the face image of the user acquired by the acquisition unit, the user who is within a first distance from the apparatus; a tracking unit tracking the user authenticated by the authentication unit; and a control unit causing the display to display a screen that is based on information corresponding to the user tracked by the tracking unit when the user has reached a position at a second distance from the apparatus, the second distance being shorter than the first distance.

Image forming apparatus, method for controlling image forming apparatus, and storage medium storing computer program

An image processing apparatus capable of suppressing degradation of the image quality of output image data, caused by electrostatic noise, without increasing a circuit scale. The image processing apparatus transmits image data obtained by reading an original, in synchronism with a synchronization signal. Noise in the synchronization signal is detected and eliminated. An image is printed using the image data. The number of times of detection of the noise is counted, and a notification indicative of the number of times of detection of the noise is made.
