摘要： A particle collecting device includes a duct; a blower configured to cause air to flow in a predetermined blowing direction inside the duct; an ionizing device disposed inside the duct and configured to ionize particles contained in the air inside the duct; at least two electrodes extending along the predetermined blowing direction, facing each other, and disposed downstream from the ionizing device inside the duct in the predetermined blowing direction; a power supply configured to charge at least one of the at least two electrodes to cause a potential difference between the at least two electrodes; and circuitry configured to control the blower, the ionizing device, and the power supply. The circuitry stops the blower in response to an ionization operation by the ionizing device.

摘要： An image forming apparatus includes an image forming device, a driving device, an external temperature detector, an internal temperature detector, a work amount detector, and control circuitry. When a temperature detected by the external temperature detector is lower than a temperature threshold, the circuitry shifts to a first restriction state based on a work amount and temporarily stops drive of the image forming device for a period every time the amount reaches a threshold. When the temperature is not lower than the temperature threshold, the circuitry shifts to a second restriction state based on an internal temperature. In the second state, in a case where the internal temperature is higher than a first threshold, the circuitry performs an intermittent operation of repeating a pause state and a printing state, until the internal temperature falls to be equal to or lower than a second threshold being lower than the first threshold.

摘要： An apparatus body structure is installed on a floor surface. The apparatus body structure includes at least one side plate. The at least one side plate is installed on the floor surface and includes an upper side plate and a lower side plate. The lower side plate is detachably joined to a lower side of the upper side plate. A floor surface installation position of the lower side plate to be installed on the floor surface is positioned directly below a floor surface installation position of the upper side plate to be installed on the floor surface, when the upper side plate is directly installed on the floor surface without being joined to the lower side plate.

摘要： A connecting device includes a connected member and a connecting member connected to the connected member. The connecting member includes a contact portion contacting a surface of the connected member and a flat spring sandwiching the connected member together with the contact portion. The connected member includes a passage hole through which the contact portion passes, a communication hole communicating with the passage hole and narrower than the passage hole, and a holding portion disposed around the communicating hole. The holding portion holds the contact portion.

摘要： An image forming apparatus configured to perform simplex printing and duplex printing includes a recording medium ejection device, a suction duct, a blower, and a pair of rotating members. The recording medium ejection device includes a recording medium outlet through which a recording medium is ejected outside of the image forming apparatus and a recording medium reverse port through which a part of the recording medium is ejected to reverse the recording medium in the duplex printing. The suction duct includes a suction port to suck air. The blower is disposed in the suction duct and sucks air from the recording medium ejection device to the suction port. The pair of rotating members is disposed between the suction port and at least one of the recording medium outlet and the recording medium reverse port and reverses both sides of the recording medium in the duplex printing.

摘要： An image forming apparatus includes a housing, a conveying member not used in simplex printing, a duct, a blower, and control circuitry. The duct includes an intake and an opening. The intake is disposed at a first end of the duct. The intake sucks air from outside of the image forming apparatus. The opening is disposed at a second end of the duct different from the first end of the duct. The duct is disposed opposite the conveying member. The blower is disposed in the duct. The blower blows air sucked from the intake to the conveying member through the opening. The control circuitry controls the blower to blow air to the conveying member at least in the simplex printing.
