The transfer device is moved to a second inner position inside the apparatus main body and to a second outer position outside the apparatus main body. The belt contacts the first photosensitive drum with the transfer device at the second inner position. The transfer device is moved from the second inner to the second outer position when the drawer unit is moved from the first inner to the first outer position.

Abstract: An image forming apparatus includes a fixing device to heat a recording material at a use position, an opening and closing member, and a drawer unit. In a state where the fixing device is at the use position, part of the fixing device is located in a space for the drawer unit to pass through when moved from a first inner position to a first outer position so that movement of the drawer unit from the first inner to the first outer position is restricted. The fixing device is retracted from the use position to a retracted position so that the movement of the drawer unit from the first inner to the first outer position is allowed. Part of the fixing device at the retracted position is at a position higher than a position of an upper cover portion of the opening and closing member at a closed position.

Abstract: An image forming apparatus to form an image on a recording material includes an apparatus main body having a first end provided with an opening and having a second end, a fixing device to heat the recording material, an opening and closing member, a drawer unit having a first photosensitive drum, and a transfer device. When being moved from a first inner position inside the apparatus main body to a first outer position outside the apparatus main body through the main body opening, the drawer unit is to be moved in a moving direction intersecting with a rotation axis of the first photosensitive drum, and is to be moved away from the second end. When being moved from a second inner position inside the apparatus main body to a second outer position outside the apparatus main body, the transfer device is moved away from the second end.

Abstract: A sheet conveyance apparatus includes first and second conveyance paths, a conveyance roller pair, first and second conveyance guides, and a holding unit. The reverse unit reverses a sheet having passed through the first conveyance path. The second conveyance path conveys the sheet having passed through the first conveyance path between the reverse unit and the first conveyance path. The conveyance roller pair nips and convey the reversed sheet. The first conveyance guide forms the second conveyance path and the second conveyance guide forms the second conveyance path. The holding unit moveably holds the first conveyance guide. The first conveyance guide moves between a first position located at a first distance from the second conveyance guide and a second position located at a second distance. The sheet reversed by the reverse unit is conveyed toward the conveyance roller pair by the first conveyance guide located at the first position.

Abstract: A sheet discharging apparatus includes a guide member configured to guide a lower surface of a sheet, a discharge roller pair, a stacking portion, and a first moving member and a second moving member each configured to move to a first position and a second position, the first position being a position where the first moving member and the second moving member protrude downstream of the discharge roller pair in the sheet discharge direction, the second position being a position located upstream of the first position in the sheet discharge direction. Support portions of the first moving member and the second moving member in the first position protrude upward in a height direction with respect to a tangent of a lower roller of the discharge roller pair when viewed in a sheet width direction.

Abstract: In adjustment processing executed at the same period as waveform analysis processing, a CPU of a microcomputer permits an execution of the waveform analysis processing on condition that the waveform analysis processing has been completed. Thus a period of non-execution of the waveform analysis processing is ensured between a completion of preceding waveform analysis processing to an execution of next waveform analysis processing. Since low priority processing, which has been disabled to be executed, is enabled to be executed, it is possible to stop continuation of disablement of execution of the low priority processing.
