Image forming apparatus

An image forming apparatus for forming a toner image on a recording material, comprising:

• a rotatable photosensitive member;
• an exposure portion configured to expose said photosensitive member to light depending on image information to form a latent image on said photosensitive member;
• a developing portion configured to use toner to develop the latent image into the toner image;
• a feed roller configured to feed the recording material;
• a transfer portion configured to transfer the toner image from said photosensitive member onto the recording material while the recording material passes through the transfer portion;
• a fixing portion including a pair of rotatable members to form a fixing nip for conveying the recording material and configured to fix the toner image onto the recording material;
• a single motor configured to drive said feed roller, said photosensitive member, and said pair of rotatable members;
• and
• a controller configured to control said single motor,
• wherein said pair of rotatable members includes a cylindrical film and a pressure roller,
• wherein said fixing portion includes a heater provided in an inner space of said film,
• wherein the fixing nip is formed between said heater and said pressure roller through said film, and
• wherein during a period when one sheet of the recording material passes through the transfer portion, said controller reduces a rotational speed of said motor at a predetermined first timing and a predetermined second timing after the predetermined first timing so as to reduce respective rotational speeds of said feed roller, said photosensitive member, and said pair of rotatable members at the predetermined first timing and the predetermined second timing.
