    摘要: When an accepting unit is removed from a main unit, a situation of the main unit is detected whether belonging to waiting situations, operation situations, malfunction situations, or the like. A display part then displays images in accordance with the detected situations. The display part is arranged on the accepting unit that is removable from the main unit. Therefore, it is possible to change images displayed on the display part in accordance with the situations of the main unit at the time when the accepting unit is removed.

    摘要: An image forming apparatus that includes a latent image carrier, a latent image forming unit, a developing unit, a toner supplier, a toner concentration detector, a prediction calculator, and a toner supply controller. The toner supplier includes a single driving source and supplies toner to a two-component developer at a predetermined supply position by driving a toner supply member with the driving source. The toner concentration detector detects a toner concentration in the developer at a predetermined detection position located upstream of the supply position. The prediction calculator predicts changes in the toner concentration in the developer over time at a prediction position located at the supply position or downstream of the supply position and upstream of a developer feed position to the developer carrier when toner is not supplied. The toner supply controller adjusts an amount of the toner supplied based on the prediction.

    摘要: In an image forming apparatus, damage to the apparatus caused by power conduction at the time of installation is prevented. When initial adjustment at factory ends and service person moves the apparatus, a power switch is turned OFF. Using this OFF operation as a trigger, a control unit 100 reads specific information (information related to pre-processing before starting power supply to the apparatus), and displays the information on electronic paper 108.

    摘要: A fixing device according to this invention includes a heating roller, a heater driver, a thermistor, and a CPU. The heating roller has a heater and heats a recording sheet. The heater driver drives the heater. The thermistor detects a surface temperature of the heating roller. The CPU stops an operation of the heater driver when the surface temperature of the heating roller becomes higher than a predetermined temperature and, thereafter, causes the thermistor to perform detection of the surface temperature of the heating roller for a predetermined time period and issues an alarm about occurrence of a first abnormality when the surface temperature of the heating roller fails to drop in the predetermined time period.

    摘要: A speed change detection apparatus includes an image carrier for carrying a latent image, and a latent image pattern forming device for forming a latent pattern image on the image carrier. The pattern image includes periodically formed line or dot images. An alternating current conversion type surface potential sensor is provided to detect a potential of the surface of the photoconductive member. The alternating current conversion type surface potential sensor further detects a change in speed of the image carrier by detecting a moiré appearing on the latent image pattern.

    摘要: A pressing wall is provided in a part of the entire area of the first carrying chamber in which a first screw member is housed. The area is opposed to a bottom wall of the first carrying chamber on the lower side in the gravity direction of the first screw member and opposed to the side walls of the first carrying chamber on both lateral sides orthogonal to a rotation axis direction of the first screw member. In the area, a toner concentration of a K developer being carried is detected by a K toner concentration sensor. The pressing wall comes into contact with, from above in the gravity direction, the K developer, which moves from a lower side to an upper side in the gravity direction according to the rotation of the first screw member, and presses the K developer downward in the gravity direction.

    摘要: In an ion generator, a high-voltage electrode with a contact portion is disposed on a first main surface of an insulating substrate and is connected to a wire electrode, and a ground electrode covered with an insulating film is disposed on a second main surface of the insulating substrate. The ground electrode is electrically connected to a contact portion on the first main surface via a through hole. By disposing the high-voltage electrode and the ground electrode on different surfaces, the occurrence of an undesirable leakage current flowing from the high-voltage electrode to the ground electrode is prevented.
