摘要： An image forming apparatus includes a unit, a housing, an outer cover, a lock, a detector, and circuitry. The unit is disposed in the image forming apparatus. The housing stores a toner bottle and has an insertion opening and an inner cover openably closable the insertion opening. The outer cover is openably closable to expose the inner cover and the unit or cover the inner cover and the unit. The lock locks the inner cover at a closed position. The detector detects an amount of toner remaining in the toner bottle. The circuitry controls the lock to unlock the inner cover based on the amount of the toner detected by the detector.

摘要： A housing includes at least one openable cover and at least one adjacent cover. The at least one openable cover swings on a hinge to separate an interior of the housing from an exterior of the housing. The at least one openable cover has a first side edge on a side of the hinge. The at least one adjacent cover is adjacent to the at least one openable cover. The at least one adjacent cover has a second side edge neighboring the first side edge of the at least one openable cover across a gap. One of the at least one openable cover and the at least one adjacent cover includes at least one projection projecting into the gap and another one of the at least one openable cover and the at least one adjacent cover includes a recess that accommodates the at least one projection in the gap.

摘要： According to an aspect of the invention, an image forming apparatus includes an apparatus body, a sound absorbing device utilizing a Helmholtz resonator, and a hinged exterior cover operable to open and close relative to the apparatus body. The hinged exterior cover is a hinged cover configured to pivot about a pivot shaft arranged at a lower end portion of the hinged exterior cover. At least a part of the hinged exterior cover has a multiplex structure made by overlaying a plurality of plate-like members on one another. The sound absorbing device is formed by utilizing space between two plate-like members of the plurality of plate-like members making up the multiplex structure as a cavity of the Helmholtz resonator.
