Image forming apparatus

An image forming apparatus comprising:

• an image forming unit configured to form a toner image on a recording material;
• a first rotary member configured to heat the toner image formed on the recording material;
• a second rotary member cooperatively forming a nip portion with the first rotary member and configured to nip and convey the recording material while pressing the toner image at the nip portion;
• and
• a cleaning mechanism configured to clean the first rotary member,
• wherein the cleaning mechanism includes:
• a collecting roller coming into contact with the first rotary member to collect toner on the first rotary member;
• a cleaning web coming into contact with the collecting roller to clean the collecting roller;
• a pressing member configured to press the cleaning web against the collecting roller;
• a winding roller configured to wind the cleaning web;
• a first support member configured to support the cleaning web, the winding roller and the pressing member;
• and
• a second support member configured to support the collecting roller,
• wherein the first support member and the second support member are supported movably respectively,
• wherein in a case where the first support member moves by a first predetermined amount, the cleaning web is separated from the collecting roller, and
• wherein in a case where the first support member moves by a second predetermined amount which is larger than the first predetermined amount, the first support member comes into contact with the second support member and moves with the second support member integrally to separate the collecting roller from the first rotary member in a state that the cleaning web is separated from the collecting roller.

• a cleaning mechanism configured to clean the first rotary member, the cleaning mechanism including a collecting roller coming into contact with the first rotary member to collect toner on the first rotary member and a cleaning web coming into contact with the collecting roller to clean the collecting roller,
• wherein the cleaning mechanism is capable of switching to a first state in which the cleaning web is separated from the collecting roller and the collecting roller is separated from the first rotary member, a second state in which the collecting roller is in contact with the first rotary member and the cleaning web is separated from the collecting roller, and a third state in which the cleaning web is in contact with the collecting roller and the collecting roller is in contact with the first rotary member.
