摘要： A pull-in apparatus configured to pull in a unit toward a predetermined position in an apparatus body includes an arm member, a restriction member, a first action portion and a second action portion. The restriction member is movable between a lock position at which the restriction member restricts movement of the arm member in a first direction and a lock-release position at which the restriction member allows the movement of the arm member in the first direction. Movement of the restriction member from the lock position toward the lock-release position is restricted in a state in which the arm member is at a stand-by position, and is allowed in a state in which the arm member has been moved from the stand-by position in a second direction.

摘要： [Problem to be solved] To further develop a prior art cartridge.
[Solution] A cartridge includes a holding movable between a first position for stably holding a second unit in a spaced position by a first unit and a second position, and a contact force receiving portion capable of receiving a contact force for moving the holding portion from the first position toward the second position to move the second unit to a developing position, when the second unit is in the spaced position. When a predetermined tangential line is a tangential line of a surface of a photosensitive member at an intersection, which is more remote from a rotational center of a charging member, of intersections between a line connecting a rotational center of the charging member and a rotational center of the photosensitive member and the surface of the photosensitive member, as viewed along a direction of a rotational axis of the developing member, and the cartridge is divided by the predetermined tangential line into sections, a predetermined section is a section in which the rotational center of the charging member does not exist, and as viewed along the rotational axis of the developing member when the second unit is in the spaced position, the contact force receiving portion is in the predetermined section.

摘要： A charge removing unit emits light onto a surface of an image bearing member for removing charge on the surface. The charge removing unit includes a light source configured to emit the light, and a light guide that is configured to guide the light to irradiate the surface of the image bearing member with the light and has a cylindrical shape extending in an axial direction of the image bearing member. At both ends in a longitudinal direction of the light guide, one end portion and another end portion are respectively provided. The light is introduced to the one end portion. The another end portion includes an inclined surface inclining in a direction from the one end portion to the another end portion, toward a central axis of a circumference of the light guide.

摘要： An image forming apparatus includes a photosensitive member that rotates at a first speed, an intermediate transfer member that rotates at a second speed lower than the first speed, and a collecting member disposed in a state in which a fixed surface is pressed against the rotating intermediate transfer member. The collecting member collects toner remaining on the intermediate transfer member after a toner image is secondarily transferred from the intermediate transfer member to a transfer material.

摘要： 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.
