An image forming apparatus includes: a plurality of stations and a plurality of stays arranged along a first direction; and a first board support member supporting a first electric board. Each of the plurality of stations includes: a rotation shaft extending in a second direction intersecting the first direction; and a photosensitive member and a flywheel provided to the rotation shaft. The first board support member is attached to two of the plurality of stays so as to bridge a gap between the two stays, and provided, in the second direction, on a first side opposite to a second side of the flywheel on which the photosensitive member is provided. The first board support member overlaps with the flywheel of at least one of the plurality of stations when viewed from a viewpoint along the second direction.

An image forming apparatus according to the present invention includes: an image bearing member; a toner image forming portion for forming a toner image on the image bearing member; a transferring portion provided in a main body of the image forming apparatus and adapted to come into contact with the image bearing member in a transfer region, for transferring the toner image on the image bearing member to a recording material; a fixing portion for fixing the toner image to the recording material in a fixing region while nipping the recording material; an opening/closing portion which can be opened and closed with respect to the main body and which is provided with the fixing portion, the opening/closing portion allowing the recording material staying between the transfer region and the fixing region to be removed from the image forming apparatus when the opening/closing portion is in an open state and causing the fixing portion to move through opening and closing of the opening/closing portion; and a separating portion for, when the opening/closing portion is opened, separating the transferring means, which is in contact with the image bearing member, from the image bearing member.

Image forming apparatus facilitating removal of recording material from opening/closing portion

There is disclosed a thermal transfer recording apparatus capable of regulating the amount of transport of ink sheet according to the selected recording sheet, thereby maintaining uniform quality of image recording. The apparatus is provided with an ink sheet transporting mechanism, a recording sheet transporting mechanism, a thermal recording head, a selector for selecting the recording sheet, and a controller for regulating the transport amount of ink sheet according to the selected recording sheet. For a recording sheet with rougher recording surface, the transport amount of ink sheet is so regulated to increase the amount of transferred ink, thereby better covering the rougher recording surface.
