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.

Image forming apparatus

An image forming apparatus includes an image forming device; a fixing device; a first conveyance passage downstream from the fixing device in a sheet conveyance direction; a second conveyance passage downstream from the fixing device and communicating with the first conveyance passage; a sheet reversing member to reverse a conveyance direction of the sheet to the second conveyance passage; a divider to switch a route of the sheet between the first conveyance passage and the second conveyance passage; and a sheet detection sensor disposed downstream from the fixing device and upstream from the divider. The first conveyance passage includes a sheet outlet from which the sheet is ejected outside the apparatus. The apparatus further includes a ventilation passage communicating with an outside, to guide air from the outside to pass the sheet detection sensor and enter at least one of the first conveyance passage and the second conveyance passage.

An image forming apparatus includes an apparatus body including a body side connector and a removable unit removably inserted in the apparatus body. The removable unit includes a unit side connector configured to engage with the body side connector in conjunction with insertion of the removable unit into and from the apparatus body in an insertion direction and disengage from the body side connector in conjunction with removal of the removable unit from the apparatus body in a removal direction. The apparatus further includes a first holder and a second holder. The first holder holds the body side connector and restrict the body side connector from moving in the insertion direction and the removal direction relative to the first holder. The second holder holds the first holder and restrict the first holder from moving in a direction different from the insertion direction and the removal direction.

An adhesive preparation containing bisoprolol includes a backing and a pressure-sensitive adhesive layer formed on one side of the backing. The pressure-sensitive adhesive layer contains a polymer prepared through copolymerization of monomer components including a hydroxyl group-containing monomer and an alkyl (meth)acrylate monomer (component (A)), a polymer prepared through copolymerization of monomer components including a methyl methacrylate monomer and a butyl methacrylate monomer (component (B)), and bisoprolol (component (C)).

A cabinet includes a first body side engagement and a second body side engagement mounted on a body and a first cover side engagement and a second cover side engagement mounted on a cover. Slide restriction faces of the first cover side engagement and the second cover side engagement come into contact with slide restriction faces of the first body side engagement and the second body side engagement, respectively, to restrict sliding of a slider when the first cover side engagement does not engage the first body side engagement. The slide restriction face of at least one of the first body side engagement and the first cover side engagement has a length that is greater than a length of the slide restriction face of other one of the first body side engagement, the first cover side engagement, the second body side engagement, and the second cover side engagement.

Cabinet, electronic device, and image forming apparatus

A sheet feeder, which is included in an image forming apparatus, includes a sheet loader on which a sheet is loaded, a sheet feeding body to feed the sheet from the sheet loader, and a sheet separator disposed to contact the sheet feeding body. The sheet is fed at a first average sheet feeding speed at which the sheet feeding body is in contact with the sheet separator without holding the sheet with the sheet separator. The sheet is fed at a second average sheet feeding speed at which the sheet feeding body is holding the sheet with the sheet separator. The first average sheet feeding speed is set smaller than the second average sheet feeding speed.

Sheet feeder and image forming apparatus incorporating the sheet feeder

A sheet feeder, which can be included in an image forming apparatus, includes a rotary body to contact and feed a recording medium to a downstream side along a sheet conveying path, a friction body disposed facing and contacting the rotary body with the sheet conveying path interposed therebetween, the friction body forming a separation nip region with the rotary body, a receiver to support the friction body at a position opposite to the separation nip region, and multiple projections to guide the recording medium toward the separation nip region. Each of the multiple projections extends toward the rotary body at respective axial ends of the rotary body and has a top face disposed upstream from the separation nip region in a sheet conveying direction between an outer circumferential surface of the rotary body and a surface of the friction body.

A sheet feeder of a friction pad separation type, which can be included in an image forming apparatus, includes a feeder body, a rotary feed body, a separation body, a holder, and a leaf spring. The rotary feed body is disposed in the feeder body and feeds a recording medium along a sheet conveying direction. The separation body is fixed to the feeder body while facing the rotary feed body. The separation body separates the recording medium with the rotary feed body. The holder has a rotary shaft and holds the separation body while being rotatably supported by the rotary shaft. The leaf spring has a flexible deforming part that contacts an area adjacent to the rotary shaft and a line of action of a pressing force of the flexible deforming part passing close by the rotary shaft.

A sheet feeding device includes a rotary feeder to contact a first side of a sheet to feed the sheet downstream along a feed passage; a friction pad disposed opposing the rotary feeder with the feed passage interposed between the rotary feeder and the friction pad to form a separation nip, the friction pad having a first side facing the separation nip and a second side opposite the first side of the friction pad; a holder disposed on the second side of the friction pad and having a first side holding the friction pad and a second side opposite the first side of the holder; a guide support disposed on the second side of the holder; and a pair of guides disposed on the guide support to contact a second side of the sheet facing the friction pad to raise the sheet from a surface of the friction pad.

A sheet feeder includes a feeding member to contact a sheet and feed the sheet downstream in a sheet conveyance direction, a friction pad disposed facing the feeding member to contact the feeding member, and a receiving table including a pad mount to hold a side of the friction pad opposite a nip between the friction pad and the feeding member. The friction pad includes a fixed range secured to the pad mount upstream from the nip and a movable range extending downstream the nip in the sheet conveyance direction. A first friction force of the pad mount to act on the movable range of the friction pad is smaller than a second friction force of the sheet to act on the movable range of the friction pad.
