Abstract:
An image forming apparatus includes a device for forming a trace of a image fixing nip, primary transfer nip, secondary transfer nip or developing nip is formed, a detecting device for detecting a width of the nip from the trace of the nip, and a controller for controlling fixing, transferring, developing or image forming parameter in accordance with the nip width detected by the detecting device. Proper image forming conditions are provided against the change of the nip width.

Claim (Index 4):
An image forming apparatus comprising:\n an image forming portion configured to form an unfixed toner image and a recording material, said image forming portion including a rotatable image bearing member, a first transfer member, a rotatable feeding member cooperating with said image bearing member to form a first transfer nip and configured to feed the recording material carrying the toner image transferred from said image bearing member by said first transfer member, and a second transfer member cooperating with said feeding member to form a second transfer nip and configured to meet and feed the recording material and said feeding member to transfer the toner image from said feeding member onto the recording material; a fixing portion configured to fix the toner image on the recording material; an image reader; and a controller configured to set an image forming condition of said image forming portion, wherein said image forming apparatus transfers a toner image pattern for measuring a width of the nip from said image bearing member onto the recording material by said first transfer member at the first transfer nip, wherein during the second transfer nip feeding the recording material, rotation of said feeding member is stopped, and transfer operation of the toner image pattern by said second transfer member is stopped, and then the transfer operation of said toner image pattern is carried out, so that a trace of the nip of the second transfer nip is formed on the recording material, wherein said fixing portion fixes the trace on the recording material, and wherein said image reader reads a width of the nip trace toner image in a recording material feeding direction, and wherein said controller controls the image forming condition in accordance with a different between results of reading of the nip trace toner image at an end portion and a central portion of the nip trace toner image with respect to a direction perpendicular to the recording material feeding direction.
