Abstract: A sheet detecting apparatus including: a detection unit including a lever member having an abutment surface abutting a conveying sheet and a holding member configured to hold the lever member, the detection unit moved by the lever member pushed by the sheet; a first urging portion configured to urge the holding member to a waiting position after the sheet is separated from the abutment surface; a support portion configured to support the lever member movable with respect to the holding member to move the lever member to a retracted position for allowing the sheet to pass the lever member contacting a surface of the sheet when the holding member is in the waiting position; and a second urging portion configured to urge the lever member so that the lever member is moved from the retracted position to a position in which the abutment surface abuts a succeeding sheet.

Abstract: A sheet conveying apparatus including: a locking member having an abutment surface abutting a sheet to correct skew feed of the sheet; a holding member configured to hold the locking member to rotate from a waiting position when the locking member is pushed by the sheet; a roller pair configured to nip the sheet abutting the abutment surface; a first urging portion configured to urge the holding member to the waiting position; a movable support portion configured to support the locking member in a manner that the locking member is located a retracted position where the locking member contacts a surface of the sheet and allows the sheet to pass; and a second urging portion configured to urge the locking member to a position where the abutment surface abuts a succeeding sheet.

Abstract: A roller is provided includes a cylindrical shaft supported by a main assembly of an image forming apparatus or a detachable cartridge. The cylindrical shaft includes a separation region on a circumference of the cylindrical shaft, where a pair of end portions of the cylindrical shaft oppose each other or are in contact with each other with respect to a circumferential direction relative to the circumference of the cylindrical shaft, and wherein the separation region extends in an axial direction of the cylindrical shaft. In addition, a rotatable cylindrical member is mounted around an outer circumference of the cylindrical shaft and is rotatable about the cylindrical shaft while an inner peripheral surface of the rotatable cylindrical member is in contact with an outer peripheral surface of the cylindrical shaft in a region of the cylindrical shaft other than the separation region with respect to the circumferential direction.

Abstract: An image forming apparatus includes a main body of the apparatus, a cartridge support member, an openable and closable member configured to open and close an opening portion, a linkage mechanism configured to link the openable and closable member and the cartridge support member to each other, and a locking portion configured to prevent the cartridge support member from being detached from the main body of the apparatus. The locking of the cartridge support member by the locking portion is released by releasing the linkage by the linkage mechanism to move the cartridge support member relative to the locking portion.

Abstract: A belt transporting device includes a belt; first and second adjustment members provided at two respective ends of a tension roller in a belt width direction orthogonal to a direction of rotation of the belt, the first and second adjustment members each being movable by receiving a force from the belt; and a link member that interlocks the movement of the first adjustment member and the movement of the second adjustment member. If the belt is laterally shifted in the belt width direction, one of the first and second adjustment members moves by receiving a force from the belt while the other is moved by the link member such that the tension roller is tilted with respect to a driving roller.
