Foreign substance collection apparatus, process cartridge, and image forming apparatus

A foreign substance collection apparatus, comprising:

• a frame body;
• an image bearing member which is rotatably supported by the frame body and which bears a developer image;
• a first collecting member which is rotatably supported by the frame body and which collects foreign substances from a surface of the image bearing member by rotating in a state of being in contact with the surface of the image bearing member;
• a second collecting member which is rotatably supported by the frame body and which further collects the foreign substances having been collected by the first collecting member from the first collecting member by rotating in a state of being in contact with a surface of the first collecting member;
• and
• a scraping member which is provided on the frame body so as to be capable of rubbing against the second collecting member and which scrapes off the foreign substances from the second collecting member when the second collecting member is rotated, wherein the frame body includes:
• a housing portion which forms a housing space for housing foreign substances;
• and
• a conveying member which conveys foreign substances inside the housing space.

• a scraping member which is provided on the frame body so as to be capable of rubbing against the second collecting member and which scrapes off the foreign substances from the second collecting member when the second collecting member is rotated;
• and
• a third collecting member which is capable of coming into contact with the second collecting member,
• wherein the third collecting member is configured to be controlled to come into contact with an outer circumferential surface of the second collecting member during a rotation operation in which the second collecting member is rotated.

• and
• a second collecting member which is rotatably supported by the frame body and which further collects the foreign substances having been collected by the first collecting member from the first collecting member by rotating in a state of being in contact with a surface of the first collecting member,
• wherein the first collecting member and the second collecting member are rotationally driven in such a manner that, at a contact portion where the first collecting member and the second collecting member come into contact with each other, a surface of the first collecting member and a surface of the second collecting member move in opposite directions.

• and
• a scraping member which is provided on the frame body so as to be capable of rubbing against the second collecting member and which scrapes off the foreign substances from the second collecting member when the second collecting member is rotated,
• wherein the frame body includes a housing portion which forms a housing space for housing foreign substances,
• wherein the housing portion includes, in a posture during use:
• a first side surface which is positioned on a side opposite to another side that the image bearing member is provided, in a first direction perpendicular to both a longitudinal direction of the image bearing member and gravity direction;
• a second side surface which is positioned further apart from the scraping member than the first side surface in the first direction;
• and
• a connecting surface which intersects the first side surface and the second side surface and which connects the first side surface and the second side surface with each other.
