Abstract

An image forming apparatus includes an image bearing member, a transfer member, a supplying member for supplying a protective agent applied onto a surface of the transfer member, and a controller capable of controlling the supplying member. In a state in which the transfer member contacts the image bearing member during non-image formation other than during image formation in which the toner image is transferred from the image bearing member onto the recording material, the controller carried out control so that an operation in an application mode in which the protective agent supplied from the supplying member is applied onto the surface of the transfer member is executed.

Claims27

Dependent claims

An image forming apparatus comprising:

an image bearing member configured to bear a toner image;
a transfer member configured to form a transfer portion where the toner image is transferred from the image bearing member onto a recording material in contact with a surface of the image bearing member;
a supplying member configured to supply a protective agent applied onto a surface of the transfer member;
and
a controller capable of controlling the supplying member,
wherein in a state in which the transfer member contacts the image bearing member during non-image formation other than during image formation in which the toner image is transferred from the image bearing member onto the recording material, the controller carried out control so that an operation in an application mode in which the protective agent supplied from the supplying member is applied onto the surface of the transfer member is executed.

3 more elements

An image forming apparatus comprising:

a photosensitive member configured to bear a toner image;
an intermediary transfer member onto which the toner image is transferred from the photosensitive member;
a transfer member configured to form a transfer portion where the toner image is transferred from the intermediary transfer member onto a recording material in contact with a surface of the intermediary transfer member;
a supplying member configured to supply a protective agent applied onto a surface of the transfer member;
and
a controller capable of controlling the supplying member,
wherein in a state in which the transfer member contacts the intermediary transfer member during non-image formation other than during image formation in which the toner image is transferred from the intermediary transfer member onto the recording material, the controller carried out control so that an operation in an application mode in which the protective agent supplied from the supplying member is applied onto the surface of the transfer member is executed.
