  • Patent number: 12265348
    Abstract: The image forming apparatus transfers an image onto a surface of a sheet at a transfer position on a conveying path. A pair of conveying rollers convey the sheet to the transfer position. The image sensor reads the sheet upstream of the transfer position. The rotary body is disposed to face the image sensor with the conveying path interposed therebetween. The rotary body includes a background portion configured to face a reading surface of the image sensor when the rotary body is at a first rotational position, and a cleaning portion configured to come into contact with the reading surface of the image sensor when the rotary body is at a second rotational position.

  • Patent number: 12019386
    Abstract: A heating unit includes a to-be-engaged portion. A fixing unit includes an engagement portion. The heating unit or the fixing unit includes an engagement guide portion. A movement mechanism retains the heating unit in a tilted attitude when causing the heating unit to move at a position set apart from the fixing unit. The engagement guide portion causes the heating unit to rock from the tilted attitude to a reference attitude while guiding the to-be-engaged portion to the engagement portion. The engagement portion engages with the to-be-engaged portion to restrict a movement of the heating unit in a longitudinal direction. A unit bias portion retains an engagement state between the engagement portion and the to-be-engaged portion.

  • Patent number: 11803140
    Abstract: A heating unit urging member urges a first support body of a heating unit toward a second support body of a fixing unit with elastic force. The heating unit urging member brings the first support body into contact with the second support body and brings the second support body into contact with two struts. An interlocking mechanism moves the heating unit along a direction in which the heating unit and the fixing unit are arranged, in conjunction with movement of an operation portion. When the operation portion moves from a first position to a second position, the interlocking mechanism moves the first support body from a reference position where the first support body is in contact with the second support body to a retracted position where the first support body is separated from the second support body.

  • Patent number: 11782381
    Abstract: In an image formation device, a driven gear is coupled to a far end portion in a unit inserting and withdrawing direction of a rotary fixing member or a rotary pressure member of a fixing unit. A driving gear is provided in a far end portion of a fixing unit housing part and engages with the driven gear when the fixing unit is housed in the fixing unit housing part. The driving gear and the driven gear are formed so that a transmission force transmitted from the driving gear to the driven gear in a mutual engagement position has a component so directed as to horizontally press the fixing unit against columns making a pair. The fixing unit as housed in the fixing unit housing part is pressed by the transmission force against the columns and positioned in a direction orthogonal to the unit inserting and withdrawing direction.
