摘要： An image forming apparatus includes an image processing section and an image forming section. The image processing section corrects, on the basis of pieces of image data, a pixel value corresponding to an auxiliary color developer in a first pixel and thereby causes a developer amount in the first pixel to fall within a predetermined range. The pieces of image data correspond to respective developers including one or more basic color developers that configure an image and the auxiliary color developer. The developer amount in the first pixel is a total amount of the one or more basic color developers and the auxiliary color developer in the first pixel when the one or more basic color developers and the auxiliary color developer are disposed on each other. The image forming section forms an image on a transfer print medium on the basis of the pieces of processed image data processed.

摘要： An image processor includes: an information acquiring circuitry causing a first communicator to perform communication with a mobile terminal and acquires status information and identification information; an authentication circuitry performing a first authentication process on a basis of the identification information; a second communicator performing communication of image data with the mobile terminal; a display displaying an authentication waiting screen receiving an input of authentication information and a first post-authentication screen corresponding to first authentication information; and a controller selecting, on a basis of the status information, one of first and second operations on a condition that the first authentication process is successful when the display displays the authentication waiting screen. The first operation causes the display to display the first post-authentication screen. The second operation causes the second communicator to perform the communication of the image data without causing the display to display the first post-authentication screen.

摘要： An image forming apparatus includes an image forming unit, a transfer unit, and a controller. The transfer unit transfers a developer image formed by the image forming unit onto a transfer object. The controller controls each of the image forming unit and the transfer unit on a basis of printing data. The controller performs a printing control to cause a first printing operation and a second printing operation to be executed. The first printing operation forms a first developer image directed to an entire pixel region of a print image and transfers the first developer image onto the transfer object. The second printing operation forms a second developer image directed selectively to a high-gradation pixel region and transfers the second developer image onto the transfer object. The high-gradation pixel region is a pixel region, having a gradation value equal to or greater than a threshold, of the print image.

摘要： An information processing apparatus according to one or more embodiments is operable in a first power mode and a second power mode that consumes less power than the first power mode. The information processing apparatus includes: a receiver that receives a packet transmitted through a communication line; a first controller that in the first power mode controls the information processing apparatus based on packets received by the receiver, and in the second power mode receives no power supply; and a second controller that in the second power mode receives power supply, and in the second power mode controls the information processing apparatus based on packets received by the receiver. Upon receiving a predetermined type of packet, the second controller responds with a packet while staying in the second power mode.
