According to one embodiment, an image forming apparatus includes a printer, a memory, a processor, and a display. The printer forms an image according to the operation of a person. The memory stores contact history information indicating the history of contact of a person. The processor acquires information on contact infection of a virus at a site contacted by a specific person from the contact history information stored in the memory. The display shows information on the contact infection of the virus.

A powder collection container accommodates a powder discharged from a discharge port of a powder discharge device including a powder discharger provided with a shutter member that opens and doses the discharge port. The powder collection container includes a moving member that is movable between a first position where the moving member abuts against the shutter member to open the discharge port of the powder discharge device, and a second position where the moving member does not abut against the shutter member and the discharge port of the powder discharge device is not opened.

An image forming apparatus includes a first body, an image forming portion, a first conveying passage provided inside of the first body and to convey toner discharged from the image forming portion, a second body detachably connected to the first body, and a second conveying passage to convey the toner received from the first conveying passage. The second conveying passage receives the toner from the first conveying passage in the first body. The second conveying passage is projected from the first body into the second body when the second body is connected to the first body, and is detachable from the first body while leaving the first conveying passage in the first body.

An imaging system includes a housing that defines a housing space, a fuser disposed inside the housing space to fix a toner image onto a print medium, a collecting device including an ionizer and a particle filter, and a controller. The fuser is associated with operation history information. The ionizer of the collecting device includes a first electrode and a second electrode. The ionizer generates a discharge between the first electrode and the second electrode so as to charge floating particles that are discharged from the fuser. The particle filter of the collecting device collects the charged floating particles. The controller controls a current to flow between the first electrode and the second electrode due to the discharging, based on the operation history information of the fuser.

A cartridge includes a frame and a photosensitive drum rotatably supported by the frame. An opening is provided in the cartridge, with toner removed from the photosensitive drum being discharged to outside of the cartridge through the opening. A discharging passageway is provided in fluid communication with the opening and through which toner can move to the opening. A coupling member is provided inside the discharging passageway, with the coupling member including a projection at an end of the coupling member, and the coupling member being movable along the discharging passageway between a first position and a second position.

An image forming apparatus includes a print engine, a waste toner collecting device, and a waste toner transfer auger. The waste toner collecting device includes a waste toner container, a sensor disposed on one side of the waste toner container, and a rotatable dispersing member which moves waste toner flowing into the waste toner container to another side of the waste toner container.

The present invention provides a process cartridge and an electronic imaging device. The process cartridge includes a cartridge body having an accommodating cavity; a developing roller rotatably installed in the accommodating cavity; a photosensitive drum rotatably installed in the cartridge body; a charging roller that is in contact with a peripheral surface of the photosensitive drum and is spaced from the developing roller; and a cleaning member that is located in the accommodating cavity and installed in the cartridge body, extends in a direction parallel to the charging roller, and is in contact with a peripheral surface of the charging roller. The developing roller is in contact with the peripheral surface of the photosensitive drum. The electronic imaging device includes a machine body, and the foregoing process cartridge is detachably installed thereon. The present invention can increase the utilization rate of toner and reduce abrasion of the photosensitive drum.

A toner collection device includes a toner collection container, a toner conveying passage, a side wall, a recessed sensing portion, and a detection sensor. The toner conveying passage includes a first inclined portion provided right under a toner collection port and inclined downward leftward in the left-right direction perpendicular to the up-down direction and a second inclined portion connected to a bottom end part of the first inclined portion and inclined downward frontward in the front-rear direction perpendicular to the up-down and left-right directions, with an end part of the second inclined portion on the left side in contact with the inner wall face of the toner collection container on the left side. The recessed sensing portion has an opening between a top end part of the side wall and the inner wall face of the toner collection container.
