摘要： A sheet conveyance apparatus includes a conveyance path including a first path through which the sheet is conveyed toward a sheet processing apparatus, and a second path branched from the first path, a switching guide configured to switch a conveyance route of the sheet between the first path and the second path, an air blowing unit configured to send air toward the conveyance path, and an air blowing port configured to blow the air from the air blowing unit to the conveyance path. The air blowing port is arranged upstream of the switching guide in a sheet conveyance direction of the first path, and configured to blow the air toward a downstream side in the sheet conveyance direction.

摘要： A sheet conveyance apparatus includes a controller controlling a driver to cause a guide to start rotation in a state in which a trailing end in a sheet conveyance direction of a preceding sheet conveyed by a roller pair having a first roller and a second roller such that the trailing end of the preceding sheet is moved from the position above a first guide to a position between a second guide and a sheet support by the rotation of the guide and that a succeeding sheet conveyed by the roller pair subsequently to the preceding sheet passes the position above the first guide after the rotation of the guide. The first roller is rotated by a driving force supplied from a driving source, and the guide rotates about a rotation axis of the first roller while rotating relatively to the first roller.

摘要： 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.

摘要： An image forming apparatus includes an image fixing device having a nip; an air blower for feeding air for cooling a first area which is an end portion area, in a longitudinal direction of the fixing device, of the nip; a blocking member for changing a width of an opening through which the air flows; a first blow portion through which the air toward the opening; a second blow portion through which the air from the air blowing device toward a second area which is a region in a widthwise direction of the sheet passed through the nip flows; and a third blow portion through which the air from the air blower toward a third area which is closer to an end in the widthwise direction flows. The third blow portion is disposed at a position to take the air blocked by the blocking member.

摘要： A sheet conveyance apparatus includes a controller controlling a driver to cause a guide to start rotation in a state in which a trailing end in a sheet conveyance direction of a preceding sheet conveyed by a roller pair having a first roller and a second roller such that the trailing end of the preceding sheet is moved from the position above a first guide to a position between a second guide and a sheet support by the rotation of the guide and that a succeeding sheet conveyed by the roller pair subsequently to the preceding sheet passes the position above the first guide after the rotation of the guide. The first roller is rotated by a driving force supplied from a driving source, and the guide rotates about a rotation axis of the first roller while rotating relatively to the first roller.

摘要： An image forming apparatus includes an apparatus body and a unit detachably mounted to the apparatus body and comprising a unit body, a cam, a first movement member, and a second movement member. The unit includes a first contact portion, an urging portion, and a second contact portion. The second movement member is attachable to the first movement member in a first manner or a second manner. A detection pattern of a detection signal differs between a state in which the second movement member is in contact with the first contact portion and a state in which the second movement member is in contact with the second contact portion, and differs between a state in which the second movement member is attached in the first manner and a state in which the second movement member is attached in the second manner.

摘要： An image forming apparatus includes a main assembly and a unit detachably mountable to the main assembly. The main assembly includes a positioning portion. The unit includes a portion-to-be-positioned engaging with the positioning portion and a grip portion configured to be gripped by a user when the unit is demounted from the main assembly. The main assembly further includes an inclined surface provided immediately in front of the positioning portion with respect to a mounting direction of the unit to the main assembly and configured to guide the portion-to-be-positioned to the positioning portion. The grip portion includes a grip surface configured to receive a force exerted in a pulling-out direction of the unit by the user when the user pulls out the unit from the main assembly. The grip surface and the inclined surface form an angle of substantially not less than 90°.

摘要： A sheet conveyance apparatus includes a guide member rotatably provided above a supporting portion and including a first guide portion and a second guide portion. The sheet conveyance apparatus further includes a controller configured to control a driving portion to start a rotation of the guide member in a state in which a trailing end of a preceding sheet is at a position above the first guide portion such that the trailing end of the preceding sheet is moved from the position above the first guide portion to a position between the second guide portion and the supporting portion by the rotation of the guide member and that a succeeding sheet conveyed by the conveyance member subsequently to the preceding sheet passes the position above the first guide portion after the rotation of the guide member.
