The developing bias of the next developing device 34 is increased to prevent the overplating and for maintaining development processing for the corresponding color image, the increase of a voltage for forming a related image is required as well. For instance, the developing bias applied to the developing device 24 is lower than that applied to the developing device 34. The developing bias for a fixed developing device is selected and controlled to be substantially equal to or a little higher than a background voltage produced by the cycle of development, reelectrification and the formation of the image.

Title: Avalanche photodiode
Inventor: MATSUMOTO KENJI
IPC: H01L31/107
Filed: 1989-03-28
Abstract: PURPOSE:To provide an avalanche photodiode which does not yield in a guard ring part and has low operation voltage by forming a PN junction in an optical detection section in its shape where it is a hemisphere assembly, while forming the same in the guard ring section in a shape of a ring. CONSTITUTION:There are provided in an optical detection section a P-type semiconductor layer 10 for a multiplication region PN junction having higher impurity concentration than that of an InP first layer 4, and in a guard ring section around the former a P-type semiconductor layer 11 for a guard ring section PN junction having higher impurity concentration than that of the InP first layer 4. That is, the PN junction has its shape spherical near B of the optical detection section while cylindrical near C of the guard ring section. Owing to the spatial effect, an electric field is difficult to be concentrated near C compared with near B and the guard ring section is difficult to yield compared with the optical detection section. Hereby, avalanche multiplication is securely produced at the optical detection section, and allows an electric field to be concentrated at the PN junction compared with a conventional APD having a planar PN junction, Thus, voltage where the avalanche multiplication can be produced is reduced.
