A sheet conveying apparatus includes a sheet conveying path through which a sheet is conveyed, and a burr pushing portion provided on the sheet conveying path and pushing down a burr, formed at one side edge in a width direction orthogonal to a sheet conveying direction of the sheet, in the width direction. The burr pushing portion includes a contact portion coming into contact with the burrs while inclining with respect to the side edge of the sheet conveyed thereto.

An inner heating member is disposed in contact with an inner circumferential surface of a heating belt and an outer heating member is disposed in contact with an outer circumferential surface of the heating belt to heat the heating belt. A restricting member configured to restrict an orbit of the heating belt is disposed between the inner and outer heating members. Then, at least either one of an area of contact between the inner circumferential surface of the heating belt and the inner heating member and an area of contact between the outer circumferential surface of the heating belt and the outer heating member is changed to quickly change a quantity of heat applied to the outer circumferential surface or inner circumferential surface of the heating belt.

An image forming apparatus has an image bearing member; developing device for developing the image bearing member to form a toner image on the image bearing member, in a developing zone; and a transferring member for forming a nip in cooperation with the image bearing member and for transferring the toner image onto a transfer material in the nip. During a portion of a period in which the transfer material is not in the nip, an electric field is formed for transferring the toner having the same polarity as the toner image from the transferring member to a first region of the image bearing member. A discharging unit is provided for discharging a second region of the image bearing member; wherein a potential of the first region in the developing station is different from a potential of the second region in the developing zone, and a bias voltage applied to the developing unit when the first region is in the developing zone before the generation of the electric field is different from that applied when the second region having been discharged by the discharging unit is in the developing zone.

Image forming apparatus with different potentials in different

The present invention provides control means for always maintaining the transfer and separation condition of an image forming apparatus of electrophotographic type. The present invention comprises time detection means for detecting a time period elapsed after a power source of the image forming apparatus is turned OFF, judgement means for judging whether the detected result of the time detection means exceeds a predetermined time, and setting means for setting conditions of the transfer means and/or the separation means, the setting means selecting the conditions of the transfer means and/or the separation means to predetermined conditions when the judged result of the judgement means is out of a predetermined time period and adopting a previous transfer and separation condition when the judged result is in the predetermined time period.
