摘要： An image forming apparatus which can control to turn on/off a light emitting element depending on a sheet state on a manual sheet tray is provided. The image forming apparatus includes the manual feed tray on which the sheet is placed. The image forming apparatus is configured to be switchable between normal power mode and power saving mode. In the normal power mode, normal power is supplied. In the power saving mode, less power is consumed as compared to the power consumed in the normal power mode. The image forming apparatus includes a manual sheet feeding sensor which detects presence/absence of the sheet on the manual feed tray. The image forming apparatus includes a sheet length sensor S and a sheet length sensor L which include the light emitting element and a light receiving element to detect approximate sheet length of sheet placed on the manual feed tray in a conveying direction.

摘要： An image forming apparatus detecting container's dismounting. A drive unit rotates the container for replenishing toner to a development unit. An output unit outputs a first signal while a predetermined portion of the container is detected, and outputs a second signal while the predetermined portion is not detected. A decision unit decides a count of changes from the second signal to the first signal based on a toner replenishing amount. A detection unit detects dismounting of the container in a case where the first signal is changed to the second signal during not rotating. The controller stops the rotation in a case where the count of changes reaches the count decided, controls the drive unit to output the first signal in a case where containers should be exchanged, and does not control the drive unit to output the first signal in a case where containers should not be exchanged.

摘要： An image forming unit includes a first receptor, a light source, a photosensitive member, a rotational polygon mirror, a light receiving unit, an identifier configured to identify a reflection face, and a generator. An information processing apparatus includes a second receptor, a first detector, a second detector, a determiner, a corrector configured to correct image data, and an output unit configured to output corrected image data to the image forming unit. When the first change is newly detected in a predetermined period, the determiner determines, based on a time period from the second timing at which the first change is newly detected to a timing at which the second change is detected and a time period from the first timing to a timing at which the second change is lastly detected before the second timing, whether the first change is a change corresponding to the identified reflection face.

摘要： A sheet feeding apparatus includes a stacking member, an optical sensor, a detected member, and a control unit. As an amount of sheets stacked on the stacking member decreases, the detected member moves from a first position in which optical sensor light is not interrupted, then once interrupts the light, and then moves to a second position in which the light is not interrupted. Information regarding an amount of sheets transmitted by the control unit, when stored information is about the detected member in the second position, is information notifying that an amount of sheets stacked on the stacking member is less than that of information regarding an amount of sheets stacked on the stacking member transmitted by the control unit when stored information is about the detected member is in the first position.
