Abstract
An image forming apparatus comprises: an image forming unit, including an image bearing member and a toner image forming unit for forming a toner image on the image bearing member in order to form an image on a recording medium; a detector for detecting the surface potential of the image bearing member, wherein an image formation condition of the image forming unit can be changed based on the surface potentials at multiple positions on the image bearing member detected by the detector, and wherein at least one of the multiple positions falls within a recording medium interval area when the image forming unit sequentially forms an image on multiple recording mediums.
Claims17
An image forming apparatus comprising:
- image forming means, including an image bearing member and toner image forming means for forming a toner image on said image bearing member, in order to form an image on a recording medium;
- detection means for detecting the surface potential of said image bearing member,
- wherein an image formation condition of said image forming means is capable of being changed based on the surface potentials at multiple positions on said image bearing member that are detected by said detection means, and
- wherein at least one of the multiple positions falls within a recording medium interval area when said image forming means sequentially forms images on multiple recording mediums.
An image forming apparatus according to one of claims 1 to 16, wherein said recording medium interval is shorter than the circumferential length of said image bearing member.
An image forming apparatus comprising:
- image forming means, including an image bearing member and toner image forming means for forming a toner image on said image bearing member in order to form an image on a recording medium;
- detection means for detecting the surface potential of said image bearing member,
- wherein said detection means is capable of detecting surface potentials on said image bearing member at a first position and a second position that is substantially at a distance from said first position that is equivalent to ½ the circumference of said image bearing member,
- wherein an image forming condition of said image forming means is capable of being changed based on the surface potentials at the first and second positions, and
- wherein the first and the second positions fall within different recording medium interval areas when said image forming means sequentially forms images on multiple recording mediums.
