Abstract: An image forming apparatus includes a toner container, a first conveyance unit, and an apparatus main body. The apparatus main body includes a photosensitive drum, a development roller, a second conveyance unit, a toner conveyance passage, light sensor, an acquisition unit, and a control unit configured to execute an abnormality detection mode. In an abnormality detection mode, the acquisition unit acquires a first acquired value after the driving of the second conveyance unit with the driving of the first conveyance unit stopped. When the first acquired value satisfies a first condition, the acquisition unit further acquires a second acquired value after the driving of the second conveyance unit with the driving of the first conveyance unit stopped. The apparatus main body further includes a notification unit to make notification of the abnormality when the second acquired value satisfies a second condition.

Abstract: An emitter emits light such that the light crosses a conveyance path. A reflector reflects the light. A receiver receives reflected light. A determiner determines that a sheet is present on the basis of an amount of reflected light. A controller may increase a light amount of the light-emitting unit from a first light amount to a second light amount on the basis of a temperature of the light-emitting unit and a reflectance of the reflecting member. The controller may increase a receiving gain of the receiver from a first gain to a second gain on the basis of a reflectance of the reflecting member.

Abstract: An information processing apparatus including a push switch turns off a power supply state of a main body and starts shutdown processing when a first user's operation is performed on the push switch in a normal state of the apparatus. When a second user's operation is performed on the push switch during the shutdown processing, the power supply state of the main body is switched between on and off. If the power supply state of the main body is the on state when the shutdown processing is completed, first processing for restarting the main body is performed, and if the power supply state of the main body is the off state when the shutdown processing is completed, second processing for stopping power supply to the main body is performed.

Abstract: An electronic apparatus includes a power source, a power monitoring unit configured to monitor an output voltage output from the power source, an acceptance unit configured to accept a user operation to turn off the electronic apparatus, and an execution unit configured to operate using power output from the power source, execute shutdown processing in response to the user operation accepted through the acceptance unit, and execute the shutdown processing when the output voltage monitored by the power monitoring unit is lower than a threshold voltage. The threshold voltage is higher than a guaranteed operation voltage of the execution unit.
