    摘要： An image forming apparatus includes a housing, a drawer, an operation panel, and a sensor. The housing includes a first side wall having a first opening, and a second side wall having a vent and extending in a direction crossing the first side wall. The drawer supports a cartridge. The drawer is movable through the first opening between an inner position at which the drawer is accommodated in the housing and an outer position at which a part of the drawer is exposed to outside the housing. At least part of the operation panel protrudes from an outer surface of the second side wall. The sensor is arranged in the housing between the drawer and the second side wall. The sensor is configured to detect at least temperature or humidity of ambient air taken in through the vent.

    摘要： An electric device, including a chassis and an operation panel, is provided. The operation panel is disposed on a face of the chassis and has one end and the other end opposite from the one end. The operation panel includes a first capacitive touch switch configured to be responsive to a touch and a second capacitive touch switch configured to be responsive to a touch. The first capacitive touch switch has a first sensitivity for responding to the touch, and the second capacitive touch switch has a second sensitivity for responding to the touch. The second capacitive touch switch is arranged in a position closer to the one end of the operation panel than the first capacitive touch switch, and the second sensitivity of the second capacitive touch switch is lower than the first sensitivity of the first capacitive touch switch.

    摘要： A drum unit detachably attachable to an image forming apparatus includes: a frame; a photosensitive drum; a toner cartridge including a toner casing and a toner memory; a connector electrically connected to the image forming apparatus; and a relay board electrically relaying the toner memory and the connector. The toner memory performs communication according to a standard that sets a value of data on a basis of a voltage for data communication at a timing when a prescribed period of time has elapsed since the voltage has made a prescribed change. The toner memory consists of three terminals as electrical contacts. The three terminals are a power supply terminal for supplying a supply voltage to the toner memory, a ground terminal, and a data terminal for communication of data to be written into the toner memory and data to be read from the toner memory.
