摘要： A housing includes a body having an opening. The body includes a peripheral portion that abuts on the opening. A cover covers at least a part of the opening. A seal is sandwiched between the cover and the peripheral portion of the body. At least one of the cover and the peripheral portion of the body includes a corner portion and a linear portion. The corner portion has a first shape that defines one of a gap between the cover and the peripheral portion of the body and a width of the seal. The linear portion abuts on the corner portion. The linear portion has a second shape that defines the one of the gap between the cover and the peripheral portion of the body and the width of the seal. The second shape is different from the first shape of the corner portion.

摘要： An image forming apparatus includes an image bearer, an exposure device, a drive device, a cleaning body, and an exposure device holder. The exposure device is disposed on a motion trajectory between an exposure position and a retracted position and emits light to the image bearer via a lens having a lens surface at the exposure position. The drive device causes the exposure device to move between the exposure position and the retracted position. The cleaning body disposed on the motion trajectory of the exposure device tilts a cleaning surface when contacting with the lens surface of the exposure device. The exposure device holder supports the exposure device while changing an attitude of the exposure device such that the lens surface remains in contact with the cleaning surface of the cleaning body when the exposure device moves from the retracted position to the exposure position.

摘要： An image forming apparatus includes an image reading device; an image forming device including a photoconductor, a charger, an exposure device including a light-emitting element, a memory to store a first correction value for correction a light emission amount of the light-emitting element, and a driver to drive the light-emitting element, a developing device, a transfer device, and a fixing device. The image forming apparatus further includes a processor to calculate a second correction value for correcting the light emission amount, based on density data of image data of a predetermined pattern on a recording medium; calculate a third correction value for correcting the light emission amount, based on the first correction value and the second correction value; and determine, before calculating the third correction value, whether placement of the recording medium on the reading table is correct based on the density data.

摘要： An optical scanning device includes a light source configured to emit a light beam; a rotary deflector configured to perform optical scanning by reflecting and deflecting the light beam emitted from the light source while rotating; an optical system forming member configured to form a path of the light beam; and a resonator having a resonance frequency corresponding to a sound generated by rotational drive of the rotary deflector. The rotary deflector is installed in a closed space. The resonator is installed so that the sound within the closed space is absorbed.
